i have a 2600 and i wish i had bought a 3000, maybe 3200

 

3200 is ideal. right now I have a temporary 3200 in stalled and though its real loose, I giggle every time it locks.

Had a TCI3000 from back before I knew they'll blow up. Running it for a few weeks until I can get something better.
When i held it up to the flexplate it would only go in far enough to do 2 bolts. the 3rd bolt would suck it into the hole. with the housing on and not tc bolts in I needed a screw driver to turn it.
