Is the FLT level 4 tranny about the same as say the Performabuilt level 2?
I know that each is a great transmission, but in terms of the amount of hp/tq they can handle are they comparable?

 

performabuilt level 2 is capable of 700hp i believe. not sure about the FLT but its probably the same. cant go wrong with either one.

 

I dont think FLT will put a 700 hp/tq rating on their level 4. Does that make a difference in build quality? No. I wouldn't let a hp/tq rating be the deciding factor for who I went with. Call em both and make a decision.

 

If you are going to try to compare PB vs FLT I would look at their level 2 vs our level 3. In my opinion our level 3 is every bit of the trans and more. See below on the details on our builds. One thing to keep in mind is hp ratings are what they are ratings. Personally I do not believe in advertising units this way. Seems more like a sales pitch when putting a rating on a trans.

we have had tried both......perfor lv2 & FLT lv4.

true story.....
we went threw a couple lv2 trans,1st went about 1500 miles & the second went a couple hundred miles & then we tried the FLT lv4.

and these were both in the same car with 407rwhp......

in OUR OPINION since we did try both companys.......since we only had to do the FLT lvl4 once,i guess we would have to say it was the better of the two.....wouldnt you?

good luck!!!!

 

Thank you Vince and heymoej.

 

FLT has excellent parts/customer service...

that is why I have their lvl 6 in my car...

 

no problem.....


if you get a new trans you might want to look @ getting a new converter to go along with it.....

looking @ your mods...maybe a yank ss3600?

what does that 3000 fuddle actually stahl too?

good luck & let us know how it works out for you!

 

I would do a PerformaBuilt lv2 with your mods that would be a perfrect tranny. I ran a perfromabuilt with 700 hp in my old set up for 3 years with no issues and ran over 200 bottles of juice and have sevaral low 10 sec passes.

Here is my is my LV2 tranny 3500 nitrous stall with a 150 shot 10.14 motor was a 370 with ms3 cam

 

while the fuddle is a small stall, it has been VERY consistant for me 60' wise.
My car dead hooks out of the hole and my 60' is a 1.65-1.66 every time.
I will go bigger with my new tranny and I think the SS3600 would be about right, allthough I will probably need some suspension work to keep my consistancy.

 

That is impressive.

 

I seriously do not think a 60e will hold up to 700 hp in a full weight car and putting street miles on it. I have been thru 11 from just about all builders except PB. Longest it i got one to last was 7 thousand miles 17 dyno runs and 120 lbs of nitrous. 3/4 wont hold. does good for couple of passes then starts flairing up. shifts all day on motor. Car only make 430 hp and 250 extra on gas. I wish i could get trans builder to just let me pay them for parts and ill put it to the 700 hp test and see for real. I have tried vac mod and man pres doesnt work. clutches and steels of all dif makes and thickness. Best so far is red eagle and kolleen 9 clutch stack up .28 tolerance endplay. Not bashing thread so please dont think so just wish i could figure out how to make it stay together and also not have to buy 11 before its rights thanks

 

The torque kills the tranny's,not hp. a 250 shot could easilly hit 800ft/lbs.Then multiply that with the converter which could easilly hit over 1000ft/lbs load on the tranny.

Time for a 4L80.

 

Can some of the vendors come in and maybe address the issue of that kind of power and the weight of a full size car? I'm curious to know what is the upper limit of a fully built 4L60E or 65E.

 

I can't believe you actually put in 11 60e's in your car Yeah, about time for an 80e or TH350, TH400

 

I know, I would have stopped at 10

 

lol id call and tell them i smoked it and they would want it back and long story short got my money back. 4l60e just wont last in a heavy car with any kind of power. i seriously think that 400 is pushing it even with good parts. maybe if you drove it around like an old man all day it would last but as far as nitrous goes or trying to run good numbers no i dont believe it. It take alot of hp and a lot of torque to push these cars into the 11's 10's or hell the nines. Yeah not saying it wouldnt make a 9 second trip just one time but at 2k a trip the glide and turbo sounds better. Heat and torque vs the weight of these sleds kill the tranny. I would like to hear some vendors on this situation

 

I have never personal dealt with PB, but I know one guy that had went through soo many transmissions on his procharged GTO that he sold it! Now I have dealt with FLT and their customer service is like one you won't find anywhere else! Twice I have drove down there to have them freshen up a trans. They set aside the whole entire day just for my transmission.

Vince, Chuck, and Andy are standup guys and would never steer anyone into something they don't need, while making sure you get the right transmission for you application!

 

I have close to 100 mid 9 second passes on my FLT transmission at over 3500 lbs.. Chuck and Vince know what they are doing. FLT gets my vote.

 

Which FLT 4L60E do you have?
