03 Dmax has the Allison Transmission. The most popular intakes are the AFE Kits or the Airaid Kits. Most people shine away from the K&N Intakes and Filters.

Luke!!!!! Come On Man!!!!!

hehehe

It has the 5spd Allison LCT1000! Its a very high quality tranny, but will only handle approx. 100HP over factory! These beast are expensive, Dont take a chance with one! ......Wait.......I make 500 on one in my work truck....and its stock.....


I dont recomend that, but it just goes to show how tough they are!

At 500hp that stock tranny isnt going to last long. (Dont ask me how I know this) How many times have you limped it?

About.....i dunno 50
Its on its last legs, It hauls 18,000-19000lbs all day long! With a Mike L Seatrab Cooler on it it never see's over 150 Deg!

Its done great but last time I changed the filter it was full of peices !

I will say , it's not ran on higher levels but the charger still trys to blow right through it!
