Ok, I put a 6.0 ltr in my 99 Formula. I have a 4l60e w/ a tci 3500 stall. After the install of everything it all ran great. Shifted fine through all gears. All of a sudden one day it just started slipping at the stall point, right around 3k rpm's. Perfectly fine anywhere below those rpms, pulls great, does a burnout, shifts fine. But as soon as you give it gas and it stalls, it slips. Then just as sudden as it started slipping, it stopped slipping. It slipped for about a week, now it was perfectly fine. Until last night, I went to the store, everything fine on the way there, then when I left, it started slipping again. Anyone have any ideas? Must be electrical right? Tranny was rebuilt a few thousand miles ago.

I have a full tune. The trans. fluid looks and smells good. Brand new TCI 3500 stall.
Is there anything electical that could cause a tranny to slip??? I took an alarm out of it and this happend 2 days later. Drove it for 5 days slipping, then it was fine for 4 days. Now it's sitting in the garage til I figure out what is going on. Someone told me there could be a seal in the trans. that could be blown and is acting like a flap, catching and uncatching. ??

It's not missing, I did have a miss, but my tuner fixed that. The motor runs perfect. No trans cooler, but it doesn't matter if its hot or cold, it will slip and not slip either way.
