Dodge Cummins! I Need help
 

i just bought a 1993 w 250 with a cummins in it but when you put it in drive it slips in and out of 3 gear. I have 1989 727 transmission that was pulled from a cummins and rebuilt but will it bolt right up to the 93? or do i even need to pull it?

Are we talking manual or auto??

auto lol sorry

When did you service it last??

the truck i just bought it yesterday lol so never the transmission i have was given to me by a farmer who sold truck he wanted to put it in but i know it has been rebuild cause he told me for one and two it has sticker on it from people who rebuilt it with all the infermation on it never been in a truck since it was rebuilt but it was rebuilt in 2007 came out of a 1989 dodge ton truck with a cummins in it

The tranny will bolt up kinda... You will loose overdrive and with out 3.07 gears the 727 will suck horribly at highway speed. It might run 60...

I would rebuild teh 518 that is in it.

its a plow truck so wonder how bad not being able to go over 60 would be since i bought truck my cash supply is limited was hopeing for a cheep fix guy climed the tranny in it was rebuilt i dont know if it could just be a sensor or if its inside the tranny itself

Make sure the transmission fluid is full, that alone can cause it to slip.
