4 Wheel Drive/SUVs/700R leak

Expert: Adam Kinion - 10/8/2009

Question
i have taken out my transmission 5 times and replaced the fly wheel, torque converter, pan gasket and filter,, and put in 2 new front seals.. The problem is i STILL have a major leak from the area of the torque converter and it has me stumped. I havew heard a few opinions that it could be some sort of bushing that is on the front shaft,, is this correct or am i missing something else ?? The fly wheel was warped and the torque converter had a crack in the neck that is why they were changed,, the vehicle is a 93 ext cab chevy 4x4 with a 90 model 700R transmission. ANY help on this would be a great help

Answer
Don, it is really hard to say what is wrong , but I would say its something in the front of the trans like a front bearing isnt in strait , or something to that affect , since you have tried so many times , good luck, why dont you take it to a trans shop and ask them to look at it for you . ADAM

Comment	just thought i would let you know that i found the problem,, it was a pump bushing that had spun in the transmission pump. To fix it remove the transmission, remove the pump from the transmission, take apart the pump and replace a 5.00 bushing,, 3.00 front seal , lock tite them in and re-install.. Just for your knowledge for future 4x4 chevy transmission problems,, since this seems to be a VERY common problem with the 700R4 , transmission
