Automatic transmission help!!!!

[B1B Keven]

Hey guys,

I just swapped a '90 318/904 into my '84 D250 (formally 318/727).

Never separated the engine from the trans. Started the motor, added

the ATF as needed and no gears!

Nothing forward or reverse.

 

Help!

i would have guessed this is a fluid issue if it worked before, was the torque converter drained? but you probably shifted through all the gears and checked the level and topped off as needed already.

sorry man.

[B1B Keven]

That's what's got me stumped. I drove the '90 up into my driveway and pulled the motor/tranny combo out.

Dropped it in my '84 and ..........nothing!!

 

Now I can't even move the shift lever on the side of the trans. LOL

Linkage is stuck in park?

[Brent B3B]

seems we had a 90 cherokee once that had a shift solenoid issue and would not let the selector move.....

do check for binding in that linkage somewhere...drop the linkage and pivot the selector bel crank by hand..if engine running...DO HAVE THE WHEELS off the ground and car/truck stationary in a safe manner...you should be able to move the selector easily...if it does not move..sounds like it is time to see what is hanging up in the valve body..

I'm thinking it's something in the valve body. With the linkage off, I can't move the shift lever.

Just don't understand why it happened.

Didja wack it and bend it when you pulled it out?

Might have to check the Rooster comb and see if you got the manual valve stuck. Its in the valve body and gets worn in and can hang up....you just die grind it smooth to allow it to move again. If that's it, it may have been the move that changed the "load" angle on the shifter that's hanging up the shifting.....hope that helps, thou I know it involves pulling the pan and stuff.

I finally had to pop the linkage out of the shifting lever to get it to move.

Still nothing.

I'm having the truck towed over to transmission shop and let them rebuild the trans.

Do you have the cooler lines hooked up? They can't just be plugged off.

 

Also the fluid needs to be checked in neutral.

Not so sure about using a 904 in a ¾ton truck. I would keep the 727.
