So Ive been having some trouble with my AW4 lately and have been testing a variety of things. My TPS checks out okay but I have the feeling it's not working "as it should".
Today I tried doing a "manual shift test" by unplugging the TCU fuse and seeing how it would react. It shifted as it "should", meaning it stays in 1st in 1-2, stays in 3rd in 3 and stays in OD in 4.
What can I deduct from this? Is my TCU fried? If it's unplugged and everything is working a-okay, does that mean it's hooped?
Heres the other question: The shifting problems have been causing me alot of grief lately, and I have taken it off the "highway" because the shifting was getting bad. Can I safely drive it on the highway in "limp home" mode as long as I watch the RPM's and manually shift it at the right times? If I start out in 1st, run to around 2400RPM and shift to 3rd after that, I don't see any problems but I thought I'd better ask.
