Default Transmission issues?

I had 3.54 gears and a 2800 stall converter installed several months back. Imediately after I got it back I drove it normal until I got the new rear gears broke in (approx. 300 miles) Once I reached the break-in period of the new gears I opened it up.

When I did this I found a new problem with my tranny. At WOT it will not shift out of "D" into "OD".

Like I said, this has been several months ago, and the tranny works absolutely flawlessly otherwise.

One thing I noticed when I developed this problem I checked the fluid level and it was a little over full, however it wasn't foaming or any bubbles, so I don't think it was extremely over full.

I recently installed a tranny cooler and I made sure the level was OK when I was finished, but I tried it again last night and it still does the same thing. Will not shift out of "D" into "OD" @ WOT.

Any ideas?

That is normal for the 4L60E series trans. At WOT they are supposed to stay in 3rd gear. I would assume the same constraint is implmented on the TV cable equipped 4L60 in your '92 (even though not electronic controlled).

:confused:

Why didn't it do it before I had the gears and TC installed?

Granted, I only took it up to those speeds twice with my 2.59 gears but both times it shifted out fine @ WOT.

You could modify the TV plunger sleeve by blocking the 4-3 part throttle passages with 2 allen screws ($.34). This will give you the 3-4 WOT shift and eliminate the 4-3 kickdown past about 85 mph (apx) with these rear end gears.

OK, thanks for the replies.

This sounds like something I could do, however, I am more concerned with, Why did it not do that before, and now it does?
