This is in a HEAVILY abused 10 second daily driver. I worry about a lot of things on my car. (stock rear end for example) but the tranny has been SOLID.
I HIGHLY recommend Yanks trannies.

<strong>Who has the best built 4L60E, P-Mac, FLP, or Yank?</strong><hr></blockquote>
You're going to get varying answers, but I'll take the FLP level IV in a heartbeat. I've tried the other two already. PMAC seems to have a nice unit, but it won't take as much power as the FLP unit will, or so it seems. Chuck does a LOT of things to the 4L60E to withstand more power. Give him a call to get the specifics. (630)820-9294
I will be giving the board a full report once I have it installed (as soon as the snow/salt clears around here).
<strong>What about the tranny that ls1speed.com offers? Does this sound like a better tranny than the FLP or Yank?</strong><hr></blockquote>
I wouldn’t call it “better” yet. It hasn’t been proven yet. We shall see as time tells though.
<strong>I have talked to a few guys on this matter. I have a TH350 built by Yank's tranny guy. I have not had any problems from mine and I have abused it hard. With talking to some guys it seems like most of the guys that have TH350 tranny problems didn't order their tranny with a Transbrake. When I spoke to Mike at Yank he told me that the trannys with T-brakes have the HD components in them even tho you didn't buy the HD built. I think that might have something to do with it.</strong><hr></blockquote>
My TH350 had a HOLE in the front of the housing that was found when we tried to put oil in it. We had to JB Weld my transmission to get it to stop leaking. <img src="images/icons/rolleyes.gif" border="0"> I won't go into the other things that took 10 extra days to get it driveable. When you pay that kind of money you should get the HD parts no matter what. It's not like a rebuild kit for a TH350 is mega bucks.
1 guy had an odd number of problems with a number of Yank trannys.
6 people have not had any problems with their Yank trannys.
It looks like Yank trannys rock.
Cool
On the upside, Tom and Carol at TByrne provided great customer support. I couldn't ask for any better.

I've sprayed over 500 rwhp many many times on two different Yank 4L60Es in 2 different F-Bodies and never had one slip on me.

What do most of the Impala SS guys run for 4L60Es? I know a good many of them want to keep OD, they all have heavy cars, and many make a lot of torque.
