Excessive clearance between the overdrive piston retainer and intermediate shaft reduces lube flow to the gear train.
Seal compensates for variations in case I.D. Oil is delivered to maximum load points on shaft. Optional oversized reverse drum journal allows salvage of reverse drum.
Sonnax is now offering an upgraded standard replacement 12962N-01K and an oversized 12962N-02K piston retainer to allow rebuilders to salvage the expensive reverse drum. The oversized piston retainer requires only turning the I.D. of the drum using a lathe and then installing as normal.
Allows damaged reverse drum to be machined and salvaged.
