Hi i am planning on overhauling my 94 gmc sierra 4x4. i want to drop a new crate 350, with multiport injection, and am looking for a good transmission to go with it. the truck is going to be used for a camping and hauling boats and fifth wheels. just need some help figuring out a good transmission to do the job

 

4l80

.

 

Or if you can do without O-Drive go with the old reliable TH-400

 

4L80e hands down

 

OW, it wont work. If he goes MP fuel injection there is no way to get upshifts in the TH400. There is no kickdown or TV lever in the MPFI set up so the controls have to be electronic. or he has to use the CFI TBI system.

 

OOPS somehow I had carb implanted in my mind. Sorry for the mis information.
