It just started yesterday. I have to let off the gas for it to shift. A couple of months ago I put in a corvette servo and a .471 boost valve and it was shifting right. What could the problem be?

Get ready it is going to let GOOOOOO!!! That is what mine started doing, in fact it was doing it when I bought it but didn't know that it was a problem. The 2-4 band is about worn out. If you do the maintenance on it you can get another year out of it. I did and make sure you drive in D and not OD for your non freeway daily driving.

Well, wait, I didn't have a 2-3 WOT upshift for 3 years, then the trans died- and it was related to a design flaw in the '86 700r4's- the pump starved for fluid.

Oops, just noticed Danny also has an '86.

I will try something, I will add a little more fluid and see what will happen. A while back it had the same problem with the 1-2 shift at WOT and I found out it was low on fluid.

I talked to Dana at www.pro-built.net and he told me the 3-4 clutch pack is on its way out. So I will be saving some money for one of his stage 2 700R4 trannys.

I now have the same problem with my 86 700r4, it happened when I floored it in OD, I somehow managed to completly burn up drive It's been like this for about 2 months now and hasn't gotten any worse (or better), but I cant stand not being able to go over 75.... I changed the filter about 2 weeks about and it was nasty metal shavings everywere, so it looks like a rebuild is gonna be done pretty soon..... unless I can find a good t56 for around $700.....
