I got a DTT trans a few weeks ago in my 97. I had it put in at JH performance in Redding. It has a billet input shaft, billet pistons and servos, and a 89% hr converter. In the last 1000 miles I have been getting mid 16's with mixed driveing. That is about 1 mpg or more up from before. Plus it shifts great. When I first got the truck it had 146k on it and was all stock. It would only get 13's. After timeing it I got up to 14 and a few 15's. Now I get solid 16's and have alot more power. Any way just letting everyone now how happy I am. Oo.
