According to factory specs, you stock lb7 has about 300 ponies.

For the millionth time, your stock transmission is only good for about 90 extra horse. so call it 390 horsepower and you will start finding tranny problems. might as well go ahead and get some upgrades for your tranny when you start adding power.

a buddy of mine from work just purchased an 05 d-max. the truck had a banks 6gun and some aftermarket intake on er' when he bought it. now, idk where your from partner but my buddy knows a guy up/down here that took his truck into his shop an for 450 bucks gave him a 5 position switch and 5 tunes to go on it. not sure which tunes he put on there but his truck now runs a hellova lot better than with the 6gun. however he was also told if he really got into it not to take it out of 3rd gear or he'd fry his tranny...personnally i dont run-round in a d-max im floppin about in a cummins which i love. however this is what i know so i hope it helps partner. :c:

Ok thanks for all the help i thought my truck was about 300hp but i wanted to make sure. btw can anyone tell what the best choice would be for a new tranny and the price to handle mid 500hp also has anyone heard of cheetah turbos thanks.

cheetah turbos are expensive :scare2: like 3200-4200 depending on what you want to do.

transmission will run you about 35-3800 with build and parts

Ok thanks for the help i knew they were expensive but i just wondered btw were can i get a tranny and what brand thanks.

I have a suncoast transmission and i like mine, had it for a few years now.

there are many vendors on the site who can help you with the transmission

Ok thanks for the advice if you don't mind me asking how much did you pay for your tranny and what stage is it i would like to get my truck in the mid 500hp range i don't know how much a tranny would cost to handle that power

my transmission was 3800 total parts and build

it was a suncoast stage 4, but they dont make those anymore, the gmax kit is just like it and itl hold the power your looking for

Ok thanks for all the help.
