tranny help

[79cherokeechief]

i have the th400 quadratrac setup. I went out today to move the jeep to clean out the garage i let it warm up put it in reverse and NOTHING? I tried all gears and tried all positions on the xfer case even neutral. when in neutral i usually get a bit of a grind sound when put back into park i dont even get that. all linkages are tight i took the inspection cover off and the convertor is spinning and the fluid level is is real high up on the dipstick?? I have never added fluid since i got it i wonder if PO overfilled due to leak. it moved on its own last week but now it does nothing ANY IDEAS??

I can't help really except, it seems strange you have no gears at all. I guess I would hope for a dirty filter at the very least.

went back out and tried it again now its working argh i hate that. im gonna try changing the filter and fluid on monday hopefully it wont happen again. i was ready to go get the gun and put it out of its misery.

If your fluid level was HIGH while it was running and you were getting nothing, I'd say your pump wasn't priming....not hyd pressure. This could be from a clogged filter...or it could be from a worn pump or a stuck pressure relief valve. Good luck.

woops...that's NO HYD PRESSURE
