I have had my transmission for 3 years and it has a little more than 7k miles on it. I am currently on my 4th 4l65e transmission on my 2005 C6 corvette. I talked to a Transmiss specialist in my area and he said I had too high of a stall. (Yank 3600 stall) I had my transmission built by Finishline. He asked me why my stall was so high and I told him that's what was recommended to me. He said drain your fluid and I bet it's black, and he said I guarantee your 3/4 clutches are burnt out because I could manually shift but no OD. I could manually shift and no overdrive. He said that's the weak link on those transmions and if you have a high stall the heat makes makes them go bad even faster. H said if I was hammering it hard at every light it would be ok, but the slower the take off the more heat with that high of a stall. I thought it would be exactly the opposite. I used the best Amsoil tranny fluid, motor oil, 2 transmission coolers, 1 stack plate, and one Derale with a fan and it still died. Does anyone know of a transmission shop that builds a transmission that can handle 6-700 hp and will last over 7k miles? Please don't say monster, 2 days and it was toast. I saw mad dog transmissions, and RPM, so far but any help would be nice. I am seriously going to drive the tires off the car with the next tranny so I can make sure it can take a beating.

RPM transmission will be able to solve your problems for you.did you ever monitor your trans temperatures in your DIC and what temperatures were you seeing?for long life do not shift it manually especially on down shift.avoid beating on it in OD.I have a 700R4 with 2400 stall that I have been running in one car for 25 years with no issues and literally 1000 passes plus street driving.car has about 20,000 miles on it and runs in the tens with 1.45 60's on 28 10.5's ET Drags.this trany is stock with an SLP shift kit in it.I run a RPM Level VI 4L65E in my C6 that is at 650rwhp.it is basically an upgraded repackaged electronically controlled 700R4
