I'm getting ready to buy one.....Need some more help making the purchase.

Race Car Driver

Great question, as I am buying a built 4L from FLP to go with my new FMS 347 nos motor setup. I have spoken with Karl Rossler about his 4L, which sells for around $2700 with core. Bottom line, I have to find a 4L that will live behind 650 fwhp. Karl said he would build a transbrake for a 4L.

Are his 4l60e trannies the real deal? I've heard so many horror stories about "built" 4l60e trannies not holding up to that kind of power and going boom. Can he build them to reliably withstand 800-900 rwhp?

For someone who wants a reliable 900 rwhp car I would probably suggest going with a Turbo 400 with a Gear Vendors overdrive.

I agree w/Phil......TH400 and grear vendors...

Oh,and yes a few have broke Rosslers $$$$ 4L60E.....

rossler 4l60e transmissions have been into the 8s...what other company can make that claim??

2MuchRiceMakesMeSick

Yep. The only way to go for that much HP...TH400

How much power do you plan on making exactly?

carl wanted something like $3300 w/o a core for his 4L60E when I spoke with him a few weeks, so I decided to go with FLP's 4L. But if i break FLP's I guess I'll call Carl. We run his TH210 in our Firebird.

i'd like to know who's run an 8 with a 4l60e. heck, i'd like to know of one that will even take mid 9's or quicker consistantly. i really find that one hard to believe. also, if it's true, how long did it last? i would think that if it could be done by one company, it could be done by more, and we would ALL know about it and have one! i'd really like to know if you would.

thanks,
Dave

Supposidly Rossler had one in a LPE TT C5 that went high 8s. Though I believe that was only done once. We are going to be pushing our shop C5 to the limits with a turbo system. We are shooting for high 8s with our Level 5 4L65E. Come this spring we should see how well our level 4 holds up when I begin hitting mine with a 300 shot.

I know there are some great companys out there buliding a 4l60e.If your going to run 9s or 8s you better start thinking turbo 350 or 400.I think a 4l60e is good for a 10s car been there done that.Im not one for breaking **** to prove points.If rossler or any company can say are tranny will hold a 9s car all day then id go for it.

believe it dave. it did it more than once also. it was Ling. TT Vette. carl told me that they were having trouble making the tranny last more than a couple of passes, that is until he machined an input shaft along with other things. thats a true custom 4L60E. not to much is left stock in carl's 4l60e.

I put Carls top of the line transmission in last year and beat the **** out of it all year. (7000 miles and 150+ passes) This year should be the acid test. With my new 408 and a 300 shot we shall see what it can take. My car is alot heavier than a vette. The billet input and the custom 3-4 pack among other things is what sets Rossler above the rest. Plus for $545 plus any hard parts I can get it refreshed

250 shot ? maybe im just a noob but ive never heard of someone with a 250 before... how many hp does that put down? like 200?

mean02

Anyone else?

Can Rossler, or anyone else for that matter, build a 4L60-e with a trans brake that can hold up to 450 RWHP? Yank has, on this forum, more or less stated that it can't be done because the 4L is just not up to the task.

Does anyone know if it can be done? I would sure like to know what Rossler has to say about this.

maddboost

The case of a 4L60E cannot hold up to the stress of a trans brake.

Thanks for your input. Have you guys at FLP given any serious consideration to finding a way to reenforce the weak points in the case or is it simply a hopeless cause?
