Bully Dog shift kit

[Extreme lb7 Dmax]

How would the Bully Dog Shift Kit help my stock Allison transmission to hold up ?

I put the kit in my truck and I love it, the first couple days it felt like I was driving a new truck again. Only problem was the Tranny Fluid to put back in it cost as much as the kit.

Go with the transgo kit. I have heard of problems with the bullydog kit. That is just personal preference though. They are about the same price anyway. If you are just at stock power levels it is good. It might help you hold a little extra power too. I don't know the real world numbers since I haven't done anything to my tranny yet. I am just going to save up for the full upgrade so I can go a little crazy with power.

Bully Dog Kit..... Is TRANSGO.

If your afraid of the BD Kit don't use the same parts in a different box.

The transgo is a little more complete than the bullydog. Here's what comes with the transgo: Transgo® Allison Shift Kit

and here is what comes the the bullydog: Bully Dog Site | Bully Dog Product


I may not be real smart, but the transgo kit comes with a lot more stuff than that bullydog kit. Do your research before trying to call me out. They are not the same kit. It also depends on the kit you buy for...the 6 speed one yes, they may be the same, but the 5 speed is not the same. The original question was about a truck with a 5 speed in it. I was basing my information off of that.

I am with Ob_1jr on this one. Go for the trans go. We have installed several of them with great success! The trucks really respond well to them and it will help your trans hold up better to abuse. How much power are you planning to run through the trans? I only ask cause if you are going to try and run something like a PPE Hot +2, you will need more than the shift kit to use the PPE to its full capability!

I guess that was my point.... if you have heard anything negative about the shift kit (either brand), it was because someone thought $200.00 was going to make the tranny hold 700RWP HP.

I Plan on running around 450 horsepower altogether.
Thanks, For the replys

you're going to need a torque converter and a full transgo kit minimum. i would look at a suncoast stage III kit or an ATS equivalent.

the bullydog shift kit is worthless imo. your tcm will learn out of it and the trans will go back to the way it was before the kit.

Yeah, that is what some of the other forums say...Talk to Mike L. (forum member) for good information on the allison and what he recommends. He is the allison guru on this and other forums.
