Ok finnaly went and got my 89 F250.. it has a 351W in it and i belive a C6 tranny..... now my problem. It wont move. 4 hi 4 lo 2 wd it doenst have an affect at all on it.. but when you take the tranny from Park and put it into gear and try to put it back into park it starts grinding like hell... is this a bad transmission? oh yeah i had it in reverse and was playing with the t-case shifter and it died on me.. PLZ HELP thanks all

 

anyone know anything about this??

 

The grinding when put into park sounds like the park lever hitting the park gear while it is spinning, like putting into park at ??mph.

Did the speedometer register any speed?

If it did, check and see if the output shaft is there (if not, well, you know what happened ), and if it is, and is in one piece, see if it's spinning while in drive.

If it is, it's either something in the center section of the rear end, or simply an axle shaft that has broken.

If not, the ouput shaft to drive shaft connection might be bad, or it's an internal trans problem like a sheared output shaft (never seen it, but could happen).

Now.
That stalling the engine thing would be an internal problem, perhaps in the torque converter or something else in the trans, I can't think of what right now though.

If so you are lucky in that the C6 is cheap to rebuild and easy to upgrade to stronger E4OD parts.

 

no the spedo didnt register any speed... the lady i bought it from said her father in law had it moving at one time and they havent got it to move since then.. so how expensive am i looking at here to fix this thing.. should i just drop the tranny and do a rebuild on it anyways just to be safe or ???

 

asking for help agian anyone know much about trannys and t-cases give their ideas PLEASE.. im dying to get this truck rolling..

 

You didn't address the rest of arch's suggestions.

I remember when I removed my driveshaft and threw the truck in drive, the tailshaft on the transfer case started to spin, as expected. Being stupid, I threw it back in park without putting it in neutral and letting the tailshaft stop, and it made a horrible grinding noise. This is because when you normally put a vehicle in park you are stopped, and the wheels being stopped causes the driveshaft to be stopped which causes the tailshaft on the transfer case to be stopped, which causes the tailshift on the transmission to be stopped, which allows the gears in the transmission to MEET without grinding each other.

So do this. Put on the e-brake real hard. Put the truck in drive. And feel for the transmission to engage (hopefully). Then climb out and look underneath the truck. Is the rear driveshaft spinning? If it IS then you have problems either in the rear diff or a broken axle shaft. If it ISN'T then you have problems somewhere between your torque converter and the tailshaft on your transfer case. Transfer case would be my best bet.

If you run into the latter scenario, then turn the truck off, remove the driveshaft, and run the same procedure as before. Now when you put it in drive, does the tailshaft on the transfer case spin? If no: turn truck off, remove the transfer case. Repeat again. When you put it in drive now, does the tailshaft on the transmission spin? If yes, you have an internal problem in your t-case. Hope that helps.

 

helps a lot... you can fee the tranny engage when you put it into gear. i probably wont be able to get back to it till this weekend but im trying to figure out what it could be now so i know what to look for this weekend.. ill be sure to do that tho thanks a lot for the reply.. most helpful info yet
