Re: top tranny to motor bolt

I always attack those from the top side with an open ended wrench. I have enough clearance between the firewall and block to hit them. I just removed my 700r4 last weekend this way. You might want to remove/move the plug wires and starter/heater wiring to make life easier.

If you already have the driveshaft, torque arm, and crossmember out, you can let the back end of the tranny hang down a bit for clearance and use a combo of extensions with a socket and go through the tranny tunnel to hit them from the back of the tranny. I had to use this method for pulling my 4L60E in my Colorado last weekend.

Re: top tranny to motor bolt

gotta agree. do it from the top. i pull the distributor for more room then jack the rear of the trans up slightly. always seems to work for me that way.
