Re: Poor Mileage After New Transmission...

I'm sure they disconnected the battery when they replaced the trans.... that resets the EVIC.

The transmission also might not be its most efficient while it is "breaking in"

Re: Poor Mileage After New Transmission...

It's colder so you let it warm up longer, therefor using more gas = less mpg per the EVIC.

Check it out with pen and paper and see.

Re: Poor Mileage After New Transmission...

Re: Poor Mileage After New Transmission...

Yeah.....I think the EVIC was reset too. It'll take a a long while to get your average back up to 15.6 if you do mostly city driving Frankie.
