4T65E Master Rebuild Kit 1997, new other (see details) and ready to install. Fits the 4T65E. Ships fast from the USA.
A 1997 4T65E is a first-year unit. GM introduced this electronic four-speed transaxle as the successor to the 4T60E, and by now an original 1997 transaxle has typically covered a lot of miles on its first set of clutches and seals. Owners usually land here because the car slips when it is warm, bangs into Drive after sitting, has started leaking from the vent or side cover, or keeps setting a long-shift code. This master rebuild kit is listed for the 1997 4T65E and gives you the soft parts and clutch material to overhaul the unit once rather than patching it seal by seal.
A master kit is the parts list for a full overhaul: the frictions that wear, plus the gaskets, lip seals, O-rings and sealing rings that keep apply oil inside each circuit. In the early 4T65E those circuits run from the pump and valve body through the channel plate into the input, second, third and fourth clutches and the forward and reverse bands. Hardened seals and worn sealing rings bleed apply pressure, so a pack that should lock in a fraction of a second drags instead and burns. Renewing the whole set restores holding capacity across every gear at the same time. The listing names it a master rebuild kit for 1997 without an itemized count, so check the contents on arrival against your teardown before you discard old parts, and do not assume steels, bands or pistons are inside.
Check the fluid level and smell, then pull the pan. A heavy layer of friction material says the clutches are done; clean fluid with shift complaints may still be a pressure control solenoid or valve body issue. Sonnax points out that a sticking pressure control solenoid can leave the car in a near-neutral state for a moment before Drive engages, and that repeated slams into gear can break the forward band. That is worth knowing on a 1997, because a burnt band means the overhaul has to go further than seals. Our 4T65E rebuild cost guide covers what a full job involves, and the pressure control solenoid guide helps you separate a solenoid fault from worn clutches.
This kit is listed for the 1997 model year 4T65E only. Because 1997 was the first year of the design, early units can differ from later ones in small ways, and some 1997 GM front-drive cars still used the older 4T60E. Confirm you have a 4T65E by the ID tag on the case before ordering, and send us your year and VIN if you want us to check it. If your unit is a later year, the 1997-2007 version of this kit or the other versions on the 4T65E parts page may be the better match.
Strip and clean the case, inspect every drum and bushing, and check the pump gears and pocket before anything goes back together. Replace the channel plate gaskets with the plate flat and clean; GM bulletin 01-07-30-032E links 4T65E vent leaks to an improperly torqued channel plate gasket. When you install the forward band, look at the servo stroke: Sonnax says typical pin travel is about 0.400 inch and offers a pin roughly 0.200 inch longer to take up excess band clearance. If the friction module itself is worn, a 1997-2002 clutch module is an alternative to relining it, and a 1997-2002 shift kit firms up apply times while the valve body is off. Fill with Dexron VI, check the level hot, and let the PCM relearn shift adapts on a test drive.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Read the ID tag on the transaxle case or send us the VIN. Some 1997 GM front-drive cars still used the 4T60E, and the parts are not interchangeable across the board.
The listing describes a master rebuild kit for 1997 without an itemized parts count. Check the contents against your teardown when it arrives and order bands or steels separately if yours are burnt or glazed.
GM bulletin 01-07-30-032E traces vent leaks on 4T65E units to an improperly torqued channel plate gasket. The rebuild is the time to replace that gasket and check the plate for flatness.
Inspect the drums, bushings, pump and forward band. Replace anything cracked, scored or burnt, and consider the pressure control solenoid, since a sticking one can damage the forward band.
Dexron VI ATF is the current GM service fill and is backward compatible with earlier Dexron specifications. Check the level at operating temperature.
