Sudden loss of gas mileage?

hi Mark, ok after the trans is fixed check the mileage, not on the trucks computer to see where your at for sure. Then lets us know.

Dropped the truck off this morning and picked it up about an hour ago.

Turns out there was a defective valve (or solenoid) in the pump. It was causing the converter to lock up almost all the time.

I didn't know that would have an effect on mileage but since I reset the mileage and drove about 50 miles, I'm averaging a little over 12 mpg.

I'll check it over the next few days but it appears to be working correctly.

hi Mark, that is why i asked if the trans was fixed yet. I thought it might be in the trans or convertor. Glad its working correct now.

Thanks Tracy, to be honest, I didn't even think it was in the trans only because I only got 5.7 mpg on the way to tampa with enclosed trailer in tow.

Point is, that was before the tranny blew so I figured something else was going on.

But like you said, I'm glad it's working.... I was getting tired of getting less than 8 mpg.

Hi i am thinking it had the problem when you went to FLA. thats why you got chit mileage and when they rebuilt the trans the sol. worked then didn't. Sometimes its hard to find things that work then don't. Alot of times they will not set a code. The trans guy should have felt it on his road test, but it may have not done it when he drove it.
