i know the a340h are gutless but i'm about 90% sure its not suppose to be as bad as my truck is. when starting off it seems like the truck has no power. I tested out my 4wd today since i got a front drive shaft in now, and could not even make it half way up the hill shown. had the gas to the floor and truck would no go up just sat there. i know people wheel these trans so this can not be normal. Now two things i think could be the issue.

One the cable that controls line pressure is messed up when i got the trans it was pulled all the way out. I dropped the pan and saw where it was suppose to retract in but would not work.
Second i'm not sure if this is right or not but when i filled the trans up the tcase had no fluid. Had to add it like they do on a gear case.Any input would help alot
