A couple months ago I picked up a '97 F250, 2wd with the E4OD trans, as an engine donor for my blown '95 (see thread, "I think she's dead, Jim", I think she's dead, Jim...
I bought it with the understanding that the trans works fine in all four forward gears, but reverse simply 'isn't there,' according to the PO (who bought it like that from his PO, who bought it like that from HIS PO, etc.) I don't know if it's a valve body issue or a clutch issue, I just don't use it, as my PO suggested. I always go somewhere with the understanding that, wherever I park, I need to pull straight through.
I pulled the truck out of the drive to turn it around in the yard (no 3-point turns with no reverse!), miscalculated my turn radius, and bumped smack into the mailbox post. CRAP! I'm in the middle of the road, no reverse, and no going forward without demolishing the mailbox post. So, on a whim, I put it in reverse, prayed, and gave it some throttle.
And it backed up! It was like doing a neutral drop, because reverse didn't kick in until about 2k RPM, but it DID go!
Given that, can anyone tell me what this might implicate? I think it exonerates the clutches, because I don't think a burned-out clutch pack would have enough torque to do a one-wheel peel, but why does it 'wait' until a higher RPM to go into gear? The fluid is clean, smells sweet, and is at the right level (if not just a tad high). Check valve, check ball, some clogged passageway?
I'm a total noob to slushboxes, every vehicle before now has been manual, but I AM willing to learn! If you've got some suggestions, lay em on me!
