I've come to the idea, after reading some threads on here that I'm going to go with the Transgo Jr. for my '04.5 since I unfortunately can't afford a fully built tranny. I just wanted to get one last opinion from some of yall on it? I'm going to be doing EFI Live for now and as of right now thats gonna be my only mod. Thanks

It isn't worth it on the 5 speed allisons, just put that money towards your built transmission fund.
Sorry to piss in your cheerios

The Transgo, not Transgo Jr. is for the 5-speed. I have a 6 and the Jr but it's my understanding the Transgo requires removing the tranny. It's a lot less than a full kit, but worth it? Dunno, have to get opinions from 5-speed guys, like nvrplzd.

The TransGo Jr will fit the 5 speed, but doesn't help much.

They do make the full TransGo, but it requires the removal and pulling the trans apart.

Most people just opt to do a upgrade, and install a clutch kit, and better converter, if they have to pull the trans. Then it will hold decent power.

If you install a tuner, and have a heavy foot, you will limp most transmissions, with Transgo kits.

Well hell. That sucks. I guess I'll just start saving. How much power can these trannys hold stock? I know its more thaan the old Dodges lol

It will hold stock.

You can get by with 90 extra HP, if you lift on the 4 to 5 shift, and the 5 to 4 shift. That is usually where it will limp.

That was printed before the Transgo came out. I was around when all this stuff was being developed. There were some worthless valve body mods out there. When Transgo came out with their kit; everyone eventualy adopted it.
Back in 2006 I sent a Transgo jr to someone at Allison and they tested it and gave me a report. The now use the same concept in 2011 so I would assume they like the idea.

So a Transgo Jr. is about useless on a 5spd? If so, I think I'm gonna save up for a TC and valve body. That should hold a little extra. What TC is everyone liking for the 5spd?

Don't buy a valve body-- all they do is install a TransGo Jr. and charge you $700. Of course they will BS you into thinking it will hold 500 horsepower. Ha Ha
