Engine/Transmission (1994 - 1998) replace manual with auto. inj pump/

[SGastelu]

I am going to replace the p7100 inj. pump on my truck with a rebuilt out of a truck with an automatic vs. my truck with the 5 speed. If i bring the engine to tdc and replace the pump... wiill the engine run? will it just have a few less horsepower?



Going to buy the wheel puller and mirror now... . unless theres someone by new jersey that wants to help!

A P7100 pump is mechanical. The transmission type does not affect it.

trans type does affect the HP ratings. A 94/95 auto pump is 160hp whereas a manual is 175 hp. 96/97/98 pumps have 2 HP ratings, 180 and 215.



But any pump will work on another truck.

Just reading this post I have a 1996 2500 with an injection pump getting ready to go south. Can I put the 215hp pump onto my automatic? Also do I need to have the pump tested if I am going to add 370 injectors and 4k springs before installing it on my truck?

Yes a 215 pump will go on your truck but with the added horse power you plan on your auto trans it will need to be upgraded also.

Transmission type affects which pump Dodge uses, but moving the pump from an automatic to a manual will not affect the rated HP for that pump.
