My 4L60E has decided not to shift into second. Tranny guy thinks it's a band and wants like $500 to fix it. So I figured I should just buy a new stronger one and not worry about it anymore. What tranny should I use? I've heard about FLP, Yank and a little about LS1Speed's, but I'm still not sure. If anyone has one of these let me know what you think of it. Thanks.

if you want the real deal, buy a rossler 4l60e. that tranny was used to power the lingenfelter Vette to 8 sec 1/4 miles. best tranny on the market IMO.

 

I would take an FLP over any other unit. Part of that is also because I live just 45 miles away from them so it's close to home.

I love their Level IV. Best trans I've ever had. Perfect shifts, fast and firm. I'd recommend it for anyone looking for a 4L60E.

 

FLP cant survive 8 sec passes.

 

Did you look at this guys sig?

Hardly 8s, and I'm gonna go out on a limb and guess that he's not looking to run 8s in the near future with this car either. And if he is, I would not suggest using ANY 4L60E. Time to start looking at TH400s (or better) for 8s, IMO.

 

I've had no direct experience, but I've done a lot of reading on this board, and if it were me, I'd be looking at FLP level IV. It'll cost you a lot more than $500, but from what everybody says, you'll love your trans. Almost makes me wish mine was broke.

 

Has anyone else used a FLP? Mine is going out and need to start looking for one that can handle my Torque.

 

Neither can Rossler, i heard that they had to pull the tranny in the that vette about every 10-20 passes and refreshen it. To me thats not surviving.

 

You're right. My car will probably never see an 8 sec. pass, unless I win the lottery or something. My mods are just your normal bolt-ons, lid, ported TB, LT's, and a YPT4000 and 4:10 gears. And I have to have an overdrive because this is my daily driver too. And a three speed with 4:10 gears would not go so well on highway trips. I was looking at the FLP pretty seriously, but the yank sportsman didn't seem too bad either. It said it held up to 600 ftlbs. But it seems not many people have these. If anyone knows anything about them let me know. My car is still drivable, so I have some time. Thanks.

Oh, yea I forgot to add. The 12.86 @ 109 run was before LT's, PT4000, 4:10's and a Chris R. tune. Just so you don't thing my car's a turd. But anyway, I plan on putting in a cam and maybe some spray late this racing season and I noticed Ed LS1 Vert was running 11.7's and his is going out. Is the FLP gonna hold up for me? Thanks for any help.

Chris

 

What about the Pro Yank? Mine is dying fast.

 

Or Speed Inc. A4 ?

 

"you heard" incorrectly. call rossler and lingenfelter to get details.

he asked which tranny would be best, IMO that has to be rossler.

 

No tranny is going to last forever behind the HP and treatment our cars see.

IMO, go with a good built tranny and if you race/beat on it alot, expect to replace the clutches every ~2 years.

As far as the Lingenfelter car.. what worked in that car, and for how long, has little bearing on a car that is driven everyday. Yank, Speed Inc, FLP, Racing Transmissions, and even Rossler can build you a strong 4L60E.. but none are indestructable.

True, but I don't want to be replacing mine every year.

 

I've heard nothing but good things about the FLP Level IV and V.

 

You might want to check out Century Transmissions too. They do some of MTI's built tranny's. GM High Tech did an article on one of their build ups in Nov.

 

There are a few local guys that have been using the FLP Level IV in cam + bolt-on A4s for well past 20K miles of spirited driving plus a few trips to the track.

I would/do expect to get a long life out of a Level IV with just a cam & bolt-ons, so long as you take proper car of the trans. With the mods in my sig, I expect 50K+ miles out of mine, and I'm not an easy driver either (though my car sees very little track time).

Add N2O, and it's a whole new story though. Depending on how much, and how often, you could find yourself replacing clutches every season.

 

Talked to cmotorsports.com told me their level II will handle what I am running and comes with a warranty.

Anyone run one of theirs??

 

Uh, no. Rossler was in process of making the package stronger for that vette (it was a work in progress), and at first it would only get a handful of passes. Now that they have their "final incarnation" of the 4l60E with 5 planetary, it has surived track and street just fine. They are doing the exact same trany for me...$3500+ with shiping and tax, but my core was pretty beat up and needed some hard parts. Not cheap, but the best 4l60e on the market bar none. the best package is $2695, plus deep pan ($80) and 5 planetary ($500). shipping was only $68 each way. he also has a package for $2195, but I would at least go with teh $2695 package, don't really need a 5 planatary unless it is a truck (extreme weight). In a 11-12 second F-body, it should last for a long time without freshening.
