***C4 auto not shifting---need ideas ASAP***
#2
It doesnt look good. It sounds like the press had to build to get the band servo all the way. Now it is simply too far to move. It is also possible an obstruction has gotten into the return line or in the vavle body. The bands being adjusted all the way in is an indication the bands are worn out.
The only thing you can try and do your self would be drop the pan and inspect, possibly retry with new fluid.
The c4 is a simple tranny to overhaul, you'll need a clean workbench, and some paitents. It takes some time to get all the depths and clearences right. I had a bench with a hole cut in it to allow the tail shaft to sit threw, made working on trannys easyer.
A good time to upgrade to kevlar clutches, bands and a custom vavlebody.
