Look here this is what Ratlover told us.

Do you have to drop the tranny to install the cut back valve or is it as easy as the Trans go jr install.

Converter Lock-up Valve
This valve controls fluid flow to the converter clutch and reduces main line pressure from 255 PSI to 155 PSI when the converter clutch applies, In the transmission the valve allow the amount of cut-back to be controlled so that main line can be adjusted between 170 to 190 PSI.

Can't tell you just what they do but can tell you that the piece shown is for an early LB7 type Allison, not the LLY/LBZ valve you'll need.

Yes to do any pump mods the trans must come out.

OK thanks for the info.

You'll need to drop the trans to do this. At that point it would be wise to add clutches and conveter aka SC-III kit...

How much HP would the trans be good for with what i am running after that up grade .

I think MikeL has a better grasp on this, but IMHO if you try to run 450RWHP it won't hold. The answer is in adding more clutches. The Suncoast III is the minuimum upgrade that I would recommend...

I run it. Only down side is slightly higher temp. Its still very managable. Only reason I wouldnt run it is if I wasnt making power and I was the type that mostly just towed higher weight in warmer air temps......might cause the thing to run a tad warmer when you didnt need it to. Running higher HP though I dont see much downside. JMO. Dont realy know and never towed much/heavy/high ambient air temps. just your basic WAG

I do pull the travel trailer in my sig about twice a month weighing about 8000lbs loaded .So mabe i should wait untill the time comes and get a
SC level 4 or 5 but i will not run over 100hp for now hopefully i will be safe.

 

[ratlover]

When you get the higher level kits it will do those things

Its not huge and I wouldnt realy worry about it. It would still be manageable I would bet. Its just if you dont need the extra clamping power then by raising the line pressure you doing it for nothing. Make sense? It dosnt raise it a ton.

I also wouldnt pull the trans and throw that stuff in without doing other things

Thanks i think now with all this info i will just wait till i can do the whole trans. thanks guys!!!!!!
