General Guidelines - Overhaul Or Replacement
Since the repair option released to dealers in September of 1985, there has been adequate opportunity for all dealers to complete the required training in the 3-day (17001.12) and one day update (17001.16) courses for the 440-T4 transaxle. SRTA units should be utilized as the alternative to in-house overhaul for which the cost of repair would exceed the cost of a SRTA exchange.
The use of SRTA units for conditions involving shift pleasability and general performance is not usually required or practical. As additional information describing diagnosis, repair and update of these units is distributed over the next few months, the need for complete assembly replacement will be substantially reduced.
