I have a FLP biult 4L60E in my car. Recently, I went to the track and ran it a couple times. On my last run, I lost 2nd gear. It was working fine all day, no slipping and good crisp hard shifts. When I went to leave the track, I realized I lost 2nd. All it does is slip. I can drive the car fine, I just have to go fast enough in 1st, that when I let off the gas it goes right to 3rd instead of 2nd. Otherwise, everything is fine. I checked the fluid, which is full and doesn't smell burnt, and has a nice color to it still.

I am thinking that the problem is the servo, since that it really the only thing that could affect only 2nd gear. Any other opinions?

I would call Chuck at FLP, but I really can't. Long story short, I'm not happy with the customer service they gave me, and I burned my bridges with them. Nuff said.

If you spray and race a lot, no 4l60 will hold up for very long - don't matter who builds it. They are just a weak tranny. If your going to do a lot of thrashing on your car on spray, I wouldn't spend another penny on the tranny. Get a bullet proof th350 with 3:23 gears. Thats what Im going to do WHEN mine breaks.

The trans is plenty strong enough to handle the power my car is making on the bottle. It's not the trans I was dissatisfied with, it was the service I received. I'm not going to go into details about it, I'll just say I was not happy.

At this point, my car is a daily driver all year round, so a TH350 or 400 is not an option.
