Basically I had a fried stock AODE on my 94 4.6 and I replaced it with what I was told was 6 month old "rebuilt" AODE out of a 98 mustang that was owned by a guy who didn't hotrod his vehicals and only took it out to do a 5spd swap. I had to switch the MLPS, harness, and mounts from the 94 trans. When we went to bolt it up we discovered that the bolt pattern on the 98 torque converter was diffrent and that it was actually 1/2" smaller in diamiter. So we switched the TC from the 94 back in to avoid drilling the flywheel. Whats happening is I have a light whirl in 1st gear and it seems like its slightly slipping on a cold take off. Once it warms up it shifts OK but if I floor it, it seems like its sliping at the end of the gears when it shifts (over revs) but then it catches smoothly and has a nice solid accelleration. If I am just letting it accelerate normally it actually shifts OK but the TC kicks in kinda hard. I've also noticed that sometime I can't manualy kick the OD in and out when its cold (hit the button but nothing happens). I drove it on the freeway for about 400 miles this past weekend (made 30 MPG) and it felt fine and it actually feels better around town now. I'm thinking maybe it could be the old TC I'm using is crap. Normally I'd say fried clutch packs except it feels really solid once it shifts. Maybe a sticking soleniod? Any ideas would be great.
