My MPG Problem!!!!!!!
 

i finaly figured out my MPG problem, well remeber i was getting like 13-15 mpg... well it is the transmition... when i put in the tremec i did not know that it had a different drive gear in it.... which makes the odometer run slower.... hence every 10 miles i go it reads 8.2 miles = bad mialge i got the corect gear yesterday and ill be putting it in today!!!

That's good news that your found the problem :) but it sucks that Tremec didn't put the same gears in :(

Where did you purchase your Tremec? They should have told you that Tremecs have a different speedo drive gear. I think the Tremec's are 7 tooth instead of 6 in the T-5's. D&D set me up with a 20 tooth (black) speedo gear for my Tremec when I got mine last year - I called them to tell them they sent me the wrong gear (I had a 21 tooth in my T-5 w/3.55s before), and that's when they informed me that the Tremecs have a different drive gear.

Good to hear you got it figured out.
