this is a continuation to a post I began earlier located in the tire and wheel section (6 to 8 lug conversion)that was dropted. I just purchased a used 91 silverado 1500 4x4 extended cab,turns out the transmission only engajed reverse, 1st and second and then no third,its would just rev after second.So after allot of thinking decided to fix it my self. I removed the tranny and turns out it was rebuilt not too long ago.(missing parts and some kind of red sealant brushed everywhere.) My budjet is very limited so I went in search of a replacement at a local wrecking yard, took advantage of the 50% off sale weekend.After looking around for a while I found a 2wheel drive 700r4 in a 92 blazer.I removed it and brought it home along with the toque converter. I opened it and proceeded to tear down and everything looked in good condition.I removed the housing with the speedometer.And measured both tranny cases,they were same length.I knew that the output shaft had to be replaced with the shorter one from the original .So i proceded very carefully removed valve body assembly ,paying close attention not to disconnect separator plate from valve body and loose check balls.(dont have a book).the hardest part was installing the band around the input clutch housing. I plan on installing it tomorrow and will post results.Im confident everything will work, i rebuilt few transmissions before ,I just refuse to be intimidated .
