New to diesel have a 90 f-250 7.3 idi was driving an lost all gears all at once now will not engage any gear and a low humming coming from trans? Any good place to start looking? Thanks
You could pull off a transmission line and see if fluid pumps out. There probably is a way but ive never had a transmission go bad on me before so i havent done it. Maybe go to a shop and ask questions or take it in. What were you doing when it stopped working?
^^^^ Yes, I've seen/had clutches fail just like that, of course, they usually gave some warning before hand, like excessive slipping or something of the like, but when they decide to let go it is all at once.
^^^^^ This. FIRST thing, shift to Park, and see if the truck can be pushed. If it can, the transmission may be fine, and the t-case may be out.
It would also be worth trying to drive the truck in 4HI and 4LO; this would indicate yet some other possible t-case problem, or a rear driveshaft/diff issue.
We need to know ALL the truck's details & history. Click this, read the caption, and follow its suggestions:
Make sure the t-case is in a drive range, and check its fluid. Check the rear axle oil. Put the t-case in 4WD, lock the hubs, and see if the truck will drive (preferably off pavement).
Yes have tried looking the hub's an driving in 4 wheel still acts like its in neutral and the humming doesn't stop in gear or park dropped the pan and no metal in pan and the trans fluid looked clean an didt smell burnt
That means the problem is forward of the transfer case. It could be something inside the trans, the torque converter, or the flex plate. The best way to narrow it down is to pull the trans out and tear it down, unless you find a broken flex plate when the trans is removed.
