Hello,
Hoping Cline can chime in. I'm in the middle of my second 4l80e build (2000 model), this ones for a friend this time. Were using a CK performance master shift kit on this one. 2 dumb questions on this kit as I haven't used this kit before:
1) the direct drum th400 piston in the kit did not come with lip seals. The rebuild kit I ordered for this build (Alto HEG kit from ebay Cline recommended in other threads) came with molded pistons and lacked the lip seals for for the drums used in earlier models. I have the lip seals for early 4l80e left over from my first build (I used a probuilt kit from Dana on 1st build). Will these lip seals work fine? I test fit them and they fit perfect, seems good to me. Only reason I'm asking a search on LS1tech someone asked the same question and someone said not to use them on the th400 drum(no explanation given of course!).
2) the CK Kit uses a 4l80e front pump cover bushing for rear output shaft for rollerizing. I used your method on my first build by knocking in a no walk bushing from the rear and a TH350 pump needle bearing (working great thanks!). Are there any issues using the CK method as there is no lube circuits in the pump busing?
