Transgo Jr

[booxr800]

Can someone fill me in on what it does. Is it like a shift kit or just different valves to protect the trans once you start adding power? How much HP is the stock allison good for? Stock HP is around 360 right so what can you go up to before you have to start modding the trans.

It is a shift kit and increses pressure to the C3 and C4 clutches.

The generally accepted "safe" increase is about 90rwhp over stock on the LLY, LBZ & LMM. Some have lived at higher levels, and some have died at lower levels. My LLY lived with a Predator 120 tune for well over a year before I first limped it. YMMV.

Is it very hard to install. I do know how to work on stuff its just my patience usually runs low real fast.

I just installed mine last weekend it wasn't too bad at all...just go slow and pay attention to where everything goes. This write up really helped me. Also if you have a friend that's willing to help for a little while that would be nice for initially dropping the valve body and putting it back in.

My stock ally lived about 8000 miles on ppe 160 tune before it was toast but I never limped it

Boy I don't think I would make it through that. It would take me atleast two days cause I would get pissed and give up the first day. Maybe my red hair has something to do with that.

Has everyone burned up their trans once they tuned their truck. It wouldn't bother me but I don't think GM would replace it for me what is the cost of a new one.

Call Mike and he'll help you out...Buy a blond wig if you need too

I have raced about 20 times with 517 rwhp with just a transgo jr of corse I dont care if I limp it or not because Im gonna build it anyway but all you do is drain the fluid, drop the valve body, replace 2 valve, drill a hole in the plate, install everything, refill with fluid, its by far the best $180 I have ever spent on my truck

You sure make it sound easy. The trans is something I never messed with, I have rebuilt and swapped out motors and put lifts on vehicles but never messed with a trans. I seen one tore completely apart once it covered 3 work tables I knew then I didn't want to mess with them.

You dont have to take out the complete trans just the pan the computer and the valve body it took me about hour and a half to do it. I wish I had some pictures to show you

 

[wes06dmax]

and if you do it your self make damn sure you dont loose one them little balls in your valve body or you will have one mell of a hess

 

[quentomania]

For me it was scary till I did it, pretty easy actually

 

[booxr800]

Thats enough to save your trans for added power to an extent. If so I guess I could do it I have axcess to a very nice shop with a lift and everything.

itto: use grease to hold in the check balls in the valve.

Vasoline or transjel would be a safer bet.
