      4l80

      I was going to do this before i got my tko-600. I researched it quite a bit. I would forget all the electrics and run the trans go full manual kit. Any decent amount of stall speed will make lockup in the t/c pretty much useless anyway, so you dont have to worry about lockup either. You'll still get a good rpm drop in 4th w/a .75 od. Keep it simple and save headaches later, i think. But the tci ecm is a pretty cool setup. A freind has one in his sbc s-10 for the 4l60e

      lockup

      How so? I think having a higher stall makes the option of lockup that much MORE beneficial, as you can lockup the converter during cruise and not waste fuel that you normally would be with the loose converter. It also lowers temps in the trans for increased life.

      hmmmmmmm

      I was calling around today looking for a motor and tranny. Now one guy said that I would need a 2wd tranny. Isn't the 4l80e out of a 4wd truck? If so, wouldn't the tranny be run without the t-case?

      Now I'm confuzzled(lol!)

      The 4L80E is built for both 2wd and 4wd. The 4wd tranny has a shorter output shaft. If you were to compare the two side by side, you would see quite a bit of difference between the two output shafts.

      If there is a hard way to do something, I'll find it!

      Hmmm, So which one should I buy?! Hahah! oh crap. If the 2wd is the one to go with, what does it come out of?

      Followup question on the same lines:

      Is there any real internal difference between the 2wd and 4wd versions, or is it just overall length - or does the transfer case bolt directly to the tranny and there's no provision for a yoke on the 4wd version?

      According to the tranny dimensions on the TCI site, the 4x4 version lacks a place for the tranny mount (or only uses one bolt)?
