I need the Part No. for the plastic gasket that mounts between the shifter on the tranny. This thing has been the issue to my shifting problems. The plastic gasket from the heat has deformed, and started to sag right in the top gear gates (3rd, 5th, and Rev) making it difficult to shift into those gears. All along I thought I had a bad clutch master cylinder. I let you guys know if this in fact was the issue once I get the new gasket.
