I'm Running a 4hp22 on a 3.9 megasquirted V8, bought the engine from a chap who said engine gearbox were still good (I drove the rrc but was first time with autobox so couldn't really compare... was a late RRC in pretty good condition but with rear damage on the bodywork).
We installed the engine and gearbox with a dedicated air oilcooler (without fan) and an lt230 transferbox in the truck. After a year of hard work, 2 weeks ago it was the first test without problems but when we came home we had to "raise" the revs before the autobox wanted to change gears which was already strange. Due to a lack of time we could only check it today but the truck wasn't moving anymore when we put it in no mather what gear.
things we checked:
-oillevel was ok (maybe a bit to much but not a lot)
-shiftercable isn't broken
-engine still runs perfect...
What could this be? We run 39" tyres on the truck, but with a reduction of 6.5 in the diffs so shouldn't have an effect on the gearbox.
Thx for your advise!

P.S. still doubting to change to lt85 manual...
