Okay here's the circs... Marlin dual cases 4.70 in the rear. After startup the transmission spins, I put the first case in gear and it spins, put the second case in gear, the gears in both cases stop moving and the truck doesn't move. Give it gas and still nothing. When I try to shift out of gear I can feel the load on the shifter. I just don't know what the heck is going on. Any help is appreciated
When I had it out of the truck last weekend, I was able to spin everything by hand, from the rear driveshaft flange and also from the transfer case input shaft. Everything spins freely even when I put it in gear out of the truck.
No. It doesn't move forward or back. I'm gonna Jack the back wheels off the ground see if that does anything. I doubt that will help bit I'm gonna try. Thanks. Ill try and update as it goes. Would this have anything to do with the shift detent ball and spring? I don't believe that I tore it down that far, unless the ball and spring can fall out of the shifter holes on top
I checked and the detent ball and springs are in place. Now for a possibly stupid question...I have the TG speedo cable extension and it is plugged into the rear case, could that be interfering with the gears spinning and causing the lockup?
I'm thinking that the shifter key on the shift rod were not grounded enough for the 4.7 gears.
I don't think tranny pressure is your problem (unless your tranny is shot). If you have both Tcases in low the amount of torque at the wheels will over power the brakes with ease. And you really can't hook up a tranny cooler wrong, it doesn't mater which way it fluid flows threw the thing unless the hoses are both hooked up to the intake or the out but I don't think you can really do that.Does your rig roll if you have the rear tcase in neutral? If so what about when you have the tcases in high gear and the tranny in neutral?
I can push it forwards or backwards with the rear case in neutral and the transmission in park. Its like the whole thing is stuck in neutral. When I put the cases in gear, it won't roll. I just find it weird that it only spins for a couple seconds in each gear before it slows to a stop. That I would think would be transmission related because both cases are spinning for a couple seconds then stop. I think if it was case related they wouldn't spin at all and the trans would do something.
But why would the gears in the cases stop spinning when they are in neutral and I shift through the transmission gears. Wouldn't the transfer case gears still spin when I put the transmission in drive and they were in neutral? I have to put the t-cases in gear to move it right, but if they already aren't moving, then putting them in gear won't do anything? BTW thanks for everyone's information. This is killing me cuz I wanna go play.
This is hurting my head, If you have your transfercase in N and the Transmission in gear, the transmission is turning the input gear of the primary range section of the double dog T/CWont matter what the secondary T/C is in,Regardless, When the vehicle is locked up wont move, wont roll, when you put the Transmission in Drive and hit the gas does it stall out ?or does it just rev up ?
It just revs up. Sorry guys. I'm just trying to figur this out. Thanks for all your help. I'm gonna ohm out the wires I hooked up during the swap and see what I get this weekend. Thanks again.
Pull the cases, further investigate, I don't think your gonna be able to discuss the problem out of it. Either its the tcase, or the tranny, either way the tcase will need to be removed. I would also look at that tranny pan, a 1" dent could be a problem.
