Transtar Part Number: S76554D

2003 and Up Chrysler 42RLE 5 Pinion Rear Planet

To tackle chronic forward clutch drum breakage in 4R70/75W series units (model years 1992-Up), Sonnax designed the stronger, more durable Smart-Tech heavy-duty forward clutch drum. This drum, available now, is forged and much stronger than the OE stamped steel design (OE number 6L3Z-7F207-A) at less than half the price.
