700r Tranny issue
 
Hey guys, I'm hoping one of you can help me out. I finally got my new winter baby (86 short-fleet) on the road but it is struggling to stay in 4th gear. When I'm cruising down the highway at about 60 and I've barely got any pressure on the pedal it keeps shifting down to 3rd instead of staying in 4th. It seems to happen on straight, level sections of the road.... when it should be just lugging along. It will go back up into 4th if I accelerate a bit first or chop the throttle completely. I've checked the tranny fluid and it is up to par. Any suggestions would be great!
Cheers

Have you double checked the setting of the cable? Sounds like it's adjusted a bit short. Do a quick Google search, instructions for setting 'em are all over the net.

Thanks for the tip, I'll check it out. I'm not much of a transmission guy, but I'll try to figure out what that means.
Cheers

The 700 uses a different type of cable to control shifts. If it's incorrectly set, it will shift at the wrong time, can actually cause damage. They're not hard to set, just make sure you understand how to do it before you start.
