A/T - C3 Slipping or No Drive Condition
DATE: January 1, 1985TSB 85-15
SUBJECT: C-3/A4LD
Starting in 1985, the C-3 transmission now has a press-fit inner race for the rear roller clutch. This type of race is also used on the new A4LD overdrive transmission.
In the event of damage occurring to the rear inner race, the case will have to be replaced. In the C-3 unit, the early case may be used to replace the 1985 case. The A4LD will require the purchase of a new case.
Rear roller clutch problems are usually identified by a slipping or no-drive condition in the Drive and Intermediate position, while the Low range remains acceptable.
