I put a 95 e4od 4x4 in a 97 7.3 f350 would there be any other reason that it wont shift at all other then that the pump is broke. It has 16 qt's of fluid in it so its not low. Mabey the connections, everything seems to be hooked up ok. If its the pump how much would it be to fix if i bring the tranny in?

 

Have you confirmed that it's not the transfer case?

 

its in 2 high if thats what you mean and it worked last time i used it.

 

So did the transmission. Either one is equally likely to be at fault. Simple test - shift to Park and attempt to push the truck. If it rolls, t-case is no longer engaging. If the Park pin holds, should mean t-case is okay, and indeed your problem is the tranny.

Is the OD-Off light on or blinking?

 

The OD light works like it should, ill have to try this tommarow, so ur saying that the connections wont have anything to do with the tranny not working?

 

Sure, any bad connection from the PCM to the tranny will cause a shifting issue. Usu. a shifting issue that the PCM detects sets a code, however, and you'd expect to see the OD-OFF light blinking.

 

A working transmission will shift into gear in both forward and reverse with or without the electrical connections. You can leave all the plugs unplugged and the trans will still move the truck.

Is there a filter inside the pan? You can see if the pump is working by putting a pressure gauge in the test port on the driver's side of the trans, near the front, just above the pan. It has a black hex head pipe plug from the factory. The thread is 1/8" NPT.

 

Hah seen this before i took the rear cooler line off while the truck ran and nothing came out so its a pump problem.

 

The park pin holds so i asume its the tranny pump.

 

Yes, it's the pump. No flow = dead pump.
