I just rebuilt my 700r4 in my 90 Iroc w/350. This was my first attempt to rebuild it using a video from Pro-Built. I decided to do it myself because this is the 5th time it has gone out on me in 13+ years and that money adds up. The first couple of test drives after installation went good. It shifted great through all 4 gears. Now after driving it for about 5 miles the shifting goes from good to it redlining before it wants to shift in all gears. I have made sure the TV cable is adjusting according to the tech article....move the cable all the way toward the transmission then at WOT let the TV cable pull out to acheive WOT....except when i do that it doesnt need to move, it still stays all the way back at WOT. What else can cause that...overheating....governer....incorrect TV cable? Any ideas would be greatly appreciated.

 

Did you check to make sure the fluid level was still correct? I had a problem like this before and it was a leak on my trans cooler.

 

Yeah I definitely have enough fluid.

 

That geometry looks incorrect to me. I could be very well mistaken, but the way the linkage looks, by pulling the throttle cable towords the firewall...there is no way all that slack will be taken out of the TV cable. I feel its not adjusted correctly.

 

If you look close at the pics...i just found out that the bracket is connected to a sliver metal plate that is bolted to the plenum. It is used for NOS systems...which the previous owner had on it. It moves the whole set up about an inch forward from the stock location. As soon as I get a chance I am going to remove it and move it back to the stock location. I'll let you know what happens.
