Lost R,2,4 gears I have had a lot of problems with this Monster preformance built 4l60e that I put in the car back in november. It is supposed to be built to handle 500 flywheel hp.
The car is a 97 Z-28 with stock 3.23 gears and I currently have a deep pan and a B&M cooler running valvaline trans fluid in the car. Engine is stock LT1 with LT headers, EGR delete, SLP CAI, BBk 52mm TB, No cats, SLP loud mouth cat back
Today I was pulling out on to a US19 and I got on it and it tried to shift to second gear and dropped back in to first. I was all over the rev limmiter and as soon as I got out of it it shifted to third gear and would not go into forth.
I have now learned that I start in first gear from a stop and no matter how light I touch the gas it will wind 1st out to about 4k rpms and then shift to 3rd gear and it seems I have lockup in 3rd but no forth gear no matter how fast I go. I also don't have reverse. I only have 1st and 3rd.
This trans has given me trouble since day one but I have gone round and round with the builder and they keep saying it's my PCM or wire harness. It wasn't but the problems went away for a while. Keep in mind this is the 3rd different problem I have had now. It is still under warrenty but I need some ammo to go to the gun fight with them and see if I can get it replaced.
The company is eatmyshift.com or as they call thier transmissions monster. Thanks guys

Did you loose 2nd, 4th and reverse all at the same time. If so I would bet that you have an issue with a broken sunshell in the transmission. Do you know if they advertise that they use the beast sunshell? The factory shell was known for this issue and I have only seen this issue with the beast a couple of times. Vince
