auto tranny problems after rebuild. please help

[shenronzero]

hey have any of you had your auto trans rebuilt and had problems with it after you got it back?

i was getting around 300 miles to the TANK before i had my trans rebuilt since it wasnt going in reverse in the cold mornings so i just had the whole thing redone... after i got it back i was only getting 200 mile to the TANK. i changed out a bunch of stuff in my fuel system thinking the problem might be there but im still getting crap gas mileage.... have any of you had/heard about an auto trans doing that after a rebuild?

and now im doing a 5 speed swap anyways... still wondering if any of you have experienced that.

thanks for the help

You can pull codes for it.

In order to have a dramatic reduction in milage, you need to have a major malfunction that you would notice. Such as no overdrive. You might not notice converter lock up. The tach will drop like 200 rpm after you steady the throttle. If it does that, it is locking.

I think you like how it feels, and have that TPS at max voltage more often.
