TH350 Clutch Module, new and ready to install. Fits the TH350. Ships fast from the USA.
If your Turbo 350 flares between gears, slips in 2nd, or takes a long breath before it moves in Drive or Reverse, the friction plates are usually where the money goes. This TH350 clutch module is the Raybestos RCP96-036 Clutch Pack, a complete set of tan OE-replacement friction plates for the 1969-1986 TH350 and TH350C used in Chevrolet, GMC, Pontiac, Oldsmobile and Buick cars and light trucks. It is the friction side of a rebuild in one sealed card, so you are not hunting four different plate sizes one at a time.
GM built the 350 around two planetary gear sets controlled by four multiple-disc clutches, two roller clutches and an intermediate overrun band. Each clutch is a stack of lined plates alternating with steel plates, clamped by a hydraulic piston. The forward clutch is on in every forward gear, the intermediate clutch works through the intermediate roller clutch to hold the sun gear in 2nd, the direct clutch comes on for 3rd and Reverse, and the low and reverse clutch holds the rear carrier in manual Low and Reverse. RCP96-036 covers all four packs:
It is frictions only. Steel separator plates are not in the pack, so plan to reuse good steels or buy them separately.
The TH350 is a hydraulic, vacuum-modulated unit, so there are no transmission trouble codes to read. Diagnosis is done with a pressure gauge, a road test and the pan.
GM's diagnosis order is fluid level, detent cable, vacuum line to the modulator, and manual linkage, then a road test with a line pressure gauge in every range. A leaking modulator or a scored servo or accumulator bore can mimic a slipping clutch, so rule those out first with our TH350 common problems and fixes guide. If the complaint is a lazy shift into gear, the TH350 delayed engagement guide walks through pump, seal ring and filter causes that frictions will not fix.
RCP96-036 is listed for 1969-1986 TH350 and TH350C. Plate counts varied by model code: GM's manual calls for three or two intermediate plates and five or four low and reverse plates depending on the application, and the heavier 375B used five direct plates instead of four. The pack supplies the higher count, so match the number of plates you take out of each drum, not the number in the card. If you are not sure you have a 350, check the ID tag on the case or send us the year and VIN before ordering. All of our Turbo 350 parts are on the TH350 parts page.
If the direct drum shows a worn sprag race or cracked housing, a replacement TH350 direct drum saves the new plates. Refill with Dexron and check level hot; our TH350 fluid type and capacity guide has the numbers.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. RCP96-036 is the friction pack only: 9 forward and direct, 3 intermediate and 5 low and reverse lined plates. Reuse steels that are flat with even color, or buy a steel module separately if yours show heat spots.
Yes. Raybestos lists RCP96-036 for both the TH350 and TH350C from 1969 to 1986. The lockup converter does not change the clutch plates.
TH350 plate counts varied by model. GM used three or two intermediate plates and five or four low and reverse plates depending on the application. Install the same count you removed from each clutch and keep the extras.
At least 30 minutes in clean Dexron ATF before assembly so the lining is fully saturated. Dry frictions can glaze on first apply.
Piston seals, O-rings, pump hub sealing rings and all gaskets, plus the filter. Also check the 1-2 accumulator and servo bores, because a worn bore will burn the intermediate clutch again.
Often. GM's chart points to the intermediate clutch, either worn plates or the wrong plate count or piston. A cut intermediate piston seal or a worn 1-2 accumulator bore causes the same symptom, so check those during teardown.
