Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The  Fund pays transaction costs when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in the Annual  Fund Operating Expenses or in the Example tables, affect the  Fund’s performance. During the most recent fiscal year, the  Fund’s portfolio turnover rate was 99% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	The Example is intended to help you compare the cost of investing in Institutional Class, I-2, I-3, Class A or Class C shares of the Fund with the costs of investing in other mutual funds. The Example assumes that you invest $10,000 in the noted class of shares for the time periods indicated, and then redeem all your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#00687D;font-family:Arial;font-size:10.92pt;font-weight:bold;margin-left:0%;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests under normal circumstances at least 80% of its assets in a diversified portfolio of Fixed Income Instruments of varying maturities, which may be represented by forwards or derivatives such as options, futures contracts or swap agreements. Security selection, industry and sector allocation, and management of market risk within and across credit and corporate markets are expected to be the main drivers of returns over time. “Fixed Income Instruments” include bonds, debt securities, bank loans and other similar instruments issued by various U.S. and non-U.S. public- or private-sector entities. The average portfolio duration of this Fund normally varies within zero to six years. Duration is a measure used to determine the sensitivity of a security’s price to changes in interest rates. The longer a security’s duration, the more sensitive it will be to changes in interest rates.The Fund may invest in both investment grade and high yield securities (“junk bonds”) subject to a maximum of 50% of its total assets in securities rated below B- by Moody’s Investors Service, Inc. (“Moody’s”), or equivalently rated by Standard & Poor’s Ratings Services (“S&P”) or Fitch, Inc. (“Fitch”), or, if unrated, determined by PIMCO to be of comparable quality. In the event that ratings services assign different ratings to the same security, PIMCO will use the highest rating as the credit rating for that security. The Fund may invest, without limitation, in securities of foreign issuers and may also invest in securities and instruments that are economically tied to emerging market countries. The Fund will normally limit its foreign currency exposure (from non-U.S. dollar denominated securities or currencies) to 20% of its total assets. The Fund may invest up to 15% of its total assets in preferred securities, convertible securities and other equity-related instruments, including up to 10% of its total assets in common stock.The Fund may invest, without limitation, in derivative instruments, such as options, futures contracts or swap agreements, or in mortgage- or asset-backed securities, subject to applicable law and any other restrictions described in the Fund’s prospectus or Statement of Additional Information. The Fund may purchase or sell securities on a when-issued, delayed delivery or forward commitment basis and may engage in short sales. The Fund may, without limitation, seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sale contracts or by using other investment techniques (such as buy backs or dollar rolls). The “total return” sought by the Fund consists of income earned on the Fund’s investments, plus capital appreciation, if any, which generally arises from decreases in interest rates, foreign currency appreciation, or improving credit fundamentals for a particular sector or security.
Risk [Heading]	rr_RiskHeading	<span style="color:#00687D;font-family:Arial;font-size:10.92pt;font-weight:bold;margin-left:0%;">Principal Risks</span>
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	It is possible to lose money on an investment in the  Fund. The principal risks of investing in the  Fund, which could adversely affect its net asset value, yield and total return, are listed below.Interest Rate Risk:  the risk that fixed income securities will decline in value because of an increase in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio durationCall Risk:  the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons (e.g., declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality). If an issuer calls a security that the  Fund has invested in, the  Fund may not recoup the full amount of its initial investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable featuresCredit Risk:  the risk that the  Fund could lose money if the issuer or guarantor of a fixed income security, or the counterparty to a derivative contract, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligationsHigh Yield Risk:  the risk that high yield securities and unrated securities of similar credit quality (commonly known as “junk bonds”) are subject to greater levels of credit, call and liquidity risks. High yield securities are considered primarily speculative with respect to the issuer’s continuing ability to make principal and interest payments, and may be more volatile than higher-rated securities of similar maturityMarket Risk:  the risk that the value of securities owned by the  Fund may go up or down, sometimes rapidly or unpredictably, due to factors affecting securities markets generally or particular industriesIssuer Risk:  the risk that the value of a security may decline for a reason directly related to the issuer, such as management performance, financial leverage and reduced demand for the issuer’s goods or servicesLiquidity Risk:  the risk that a particular investment may be difficult to purchase or sell and that the  Fund may be unable to sell illiquid investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, and may be magnified in a rising interest rate environment or other circumstances where investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activityDerivatives Risk:  the risk of investing in derivative instruments (such as futures, swaps and structured securities), including leverage, liquidity, interest rate, market, credit and management risks, and valuation complexity. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the  Fund could lose more than the initial amount invested. The  Fund’s use of derivatives may result in losses to the  Fund, a reduction in the  Fund’s returns and/or increased volatility. Over-the-counter (“OTC”) derivatives are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for OTC derivatives. The primary credit risk on derivatives that are exchange-traded or traded through a central clearing counterparty resides with the  Fund's clearing broker or the clearinghouse. Changes in regulation relating to a mutual fund’s use of derivatives and related instruments could potentially limit or impact the  Fund’s ability to invest in derivatives, limit the  Fund’s ability to employ certain strategies that use derivatives and/or adversely affect the value of derivatives and the  Fund’s performanceMortgage-Related and Other Asset-Backed Securities Risk:  the risks of investing in mortgage-related and other asset-backed securities, including interest rate risk, extension risk, prepayment risk and credit riskForeign (Non-U.S.) Investment Risk:  the risk that investing in foreign (non-U.S.) securities may result in the  Fund experiencing more rapid and extreme changes in value than a fund that invests exclusively in securities of U.S. companies, due to smaller markets, differing reporting, accounting and auditing standards, increased risk of delayed settlement of portfolio transactions or loss of certificates of portfolio securities, and the risk of unfavorable foreign government actions, including nationalization, expropriation or confiscatory taxation, currency blockage, or political changes or diplomatic developments. Foreign securities may also be less liquid and more difficult to value than securities of U.S. issuersSenior Loan Risk:  the risk that investing in senior loans, including bank loans, exposes the Fund to heightened credit risk, call risk, settlement risk and liquidity risk. If an issuer of a senior loan prepays or redeems the loan prior to maturity, the Fund may have to reinvest the proceeds in instruments that pay lower interest rates. To the extent the Fund invests in senior loans that are covenant-lite obligations, the Fund may have fewer rights against a borrower and may have a greater risk of loss on such investments as compared to investments in traditional loansEmerging Markets Risk:  the risk of investing in emerging market securities, primarily increased foreign (non-U.S.) investment riskSovereign Debt Risk:  the risk that investments in fixed income instruments issued by sovereign entities may decline in value as a result of default or other adverse credit event resulting from an issuer’s inability or unwillingness to make principal or interest payments in a timely fashionCurrency Risk:  the risk that foreign (non-U.S.) currencies will change in value relative to the U.S. dollar and affect the  Fund’s investments in foreign (non-U.S.) currencies or in securities that trade in, and receive revenues in, or in derivatives that provide exposure to, foreign (non-U.S.) currenciesEquity Risk:  the risk that the value of equity or equity-related securities, may decline due to general market conditions which are not specifically related to a particular company or to factors affecting a particular industry or industries. Equity or equity-related securities generally have greater price volatility than fixed income securitiesConvertible Securities Risk:  as convertible securities share both fixed income and equity characteristics, they are subject to risks to which fixed income and equity investments are subject. These risks include equity risk, interest rate risk and credit riskLeveraging Risk:  the risk that certain transactions of the  Fund, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, or derivative instruments, may give rise to leverage, magnifying gains and losses and causing the  Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of lossManagement Risk:  the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory, or tax restrictions, policies or developments may affect the investment techniques available to PIMCO and the individual portfolio manager in connection with managing the  Fund and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the  Fund will be achievedShort Exposure Risk:  the risk of entering into short sales, including the potential loss of more money than the actual cost of the investment, and the risk that the third party to the short sale will not fulfill its contractual obligations, causing a loss to the  FundLIBOR Transition Risk:  the risk related to the anticipated discontinuation of the London Interbank Offered Rate (“LIBOR”). Certain instruments held by the  Fund rely in some fashion upon LIBOR. Although the transition process away from LIBOR has become increasingly well-defined in advance of the anticipated discontinuation date, there remains uncertainty regarding the nature of any replacement rate, and any potential effects of the transition away from LIBOR on the  Fund or on certain instruments in which the  Fund invests can be difficult to ascertain. The transition process may involve, among other things, increased volatility or illiquidity in markets for instruments that currently rely on LIBOR and may result in a reduction in the value of certain instruments held by the  FundPlease see “Description of Principal Risks” in the  Fund's prospectus for a more detailed description of the risks of investing in the  Fund. An investment in the  Fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency.

[1] PIMCO has contractually agreed, through July 31, 2022, to reduce its supervisory and administrative fee for the Fund’s I-3 shares by 0.05% of the average daily net assets attributable to I-3 shares of the Fund. This Fee Waiver Agreement renews annually unless terminated by PIMCO upon at least 30 days’ prior notice to the end of the contract term.

[2] After-tax returns are calculated using the highest historical individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown, and the after-tax returns shown are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. In some cases the return after taxes may exceed the return before taxes due to an assumed tax benefit from any losses on a sale of Fund shares at the end of the measurement period. After-tax returns are for Institutional Class shares only. After-tax returns for other classes will vary.
