Re: 4BT Diesel / TH400 with Gear Venders 6 spd OverDrive?
Have you made any progress on your 4BT swap? I am wanting to do the same setup in mine.
I actually have a GV unit currently in my 96 Quigley, which has a C6. It works great. Got it used on ebay for about 1/3 the price. It needed a little attention, but it works great now. The timing on the gear splits can be a little tricky, but having that 1/2 gear between the original 3 makes a big difference. I saw about a 20% improvement in fuel economy (granted it was from 10 to 12, but hey, 20% is 20%!).
I have yet to see a 4BT in a NBS E series, and am very curious how it would fit (mostly height-wise), especially on a 4WD, if it's even possible. Everyone seems to focus on the 6BT, which seems even less likely to fit, but I guess anything is possible given enough time and $$
If you have made any progress, please share!
