Transmission Rebuilt Has anyone had a transmission rebuilt by www.transmissioncenter.net. They rebuild the 4T65's with improved clutch bands and a number of other parts. I'm just curious if anyone has used them and if they are satisfied. As soon as i get my first transmission failure i'm going to purchase there Level 2 4T65 rebuilt transmission. They claim it can handle 700HP easily.

Theres only a few weak parts in 4T65 you can easily upgrade them. Its the clutch's that can't take the torque. They use clutch bands that are rated for 1000HP 2nd i'm not going to be making 700HP of course i just want a trans that can take daily abuse. But thanks for your reply's.

1. Enable the Diff. Surge protection every time the gas pedal is touched.
2. Grenade the input shaft.
3. Make mince meat of the spiders and primaries.
4. Sheer the thrust washers.
5. Leave little pieces from the exploded tranny case all over the place.
But sure dude, get your tranny built. My friend has a single turbo MCSS @10 PSI on a forged 3800 and he has rebuilt his tranny 4 times with a Quaife Posi unit each time, that alone costing $2,000. He only makes ~440 HP, ~420 TQ.
Oh and here you go:

I believe he ran LS7 injectors, some aftermarket intercooler for a Neon, and custom Magnaflow catback. I was with him when he picked it up and that thing burned the tires to about 60mph. The builder said the setup would probably do 420rwhp on 7psi and tuned with 91 octane.
Anyways, 3 days and the trans was fubar. Had the trans rebuilt by a local GTP guy using all Intense stuff and a Qauife(sp) posi.
Motor was toast in a month, car is gone, and he has a another brand new GXP that will only see bolt ons.
Turbo setup was top notch and badass. Its the car owners "zero" automotive knowledge that killed this car, not the shop that put it together.

FWD trans axle, delivering about 700-1000 HP would do horrible things:
1. Enable the Diff. Surge protection every time the gas pedal is touched.
2. Grenade the input shaft.
3. Make mince meat of the spiders and primaries.
4. Sheer the thrust washers.
5. Leave little pieces from the exploded tranny case all over the place.

Thx i wasn't even going to bother replying they don't get the picture. Not to mention i didn't say i was going to have 700HP i just want one built to withstand it so it can take my daily abuse.

It has nothing to do with that. These cars will not handle 700hp for very long, one thing will break after another. It gets back to the whole thing, if you want a race car buy one.

After the initial depreciation, it will have good value.
