Alright so as well all know our transmissions are a ticking time bomb. Mine just started jolting from 4th too overdrive. Called triple edge and ill be looking at 1900 for the tranny, 400 for shipping total plus labor and radiator. Also, 1 month till it would even make it too my car. What is gm charging to rebuild it back to crap??! Just trying to see my options. Anyone do a recent rebuild through gm?

Have you had a transmission done through them? I'm a little skeptical about getting a rebuild from a company that is not specialized in our trannsmissions

Is anyone really going to compete with a rebuild like this?? GM High Performance 4T65E
I don't think any transmission 'specialist' can make a better transmission than the TEP transmission for our cars. They are the best hands down. I'll probably get one eventually when my tranny eventually dies. I'm having my transmission fluid, filter and gasket changed soon, and I just bought the stuff from GM. I think tranny shops are throwing garbage fluid into our transmissions and making them go bad so that they can overhaul them.

depending on your use of the car GM likely has a Goodwrench reman with 100K mile warranty good at any dealer if you had trouble again.

The dealer does give you a new 5yr/100k warranty on the trans, but it's about $3k out the door. What's this part about a radiator? Something wrong with yours? All that is normally needed is to flush the cooler, just a cheap can of transmission cooler flush from the parts store.

Ya I don't know how much I believe in GM being the best to rebuild these transmissions. After all, these transmissions are all going out before 100,000 miles. Why should I believe that GM is actually taking responsibility and doing a 100% job this time around? I understand the great warranty they do but even after these rebuilds some are still going out in thirty thousand miles. I would be very curious to see their rebuild job sheet vs the one in the link I previously posted.

I had 2005 impala whit hard shift got it rebuild and it was not good rev up and down at overdrive worst hard shift in every gear.
5 time they pull the trans out. I got a jasper trans they install it and it was good. jasper test the trans before they seed it out and you know it works

they fix any factory defect and install updated part to every common problem that the trans got and 3year warranty
the dealer only fix what is damage and install new seal, gasket and new clutches

PS
install a trans cooler it will help it stay cool

Jasper has a better warranty but TEP seems to do an amazing rebuild and
I havent heard anything negative so far. The writeup on TEP rebuilds seems extremely thorough. Glad you're transmission is working out Chevy blew it on this one lol

Some good info here that Dave just sent me from TEP.


For transmission coolers- we do have a few options and it really depends which route you want to go.

The inexpensive option which allows you to bypass the radiator would be to use our $109.95 TruCool stacked plate style universal cooler kit. This cooler works well alone or in line with the radiator. This kit is a universal kit but does include mounting brackets which makes mounting no problem on these cars. The hoses are rubber transmission cooler hose with clamps that attach it, so we caution this is something that needs to be monitors regularly to assure you do not have leaks or a loose clamp. When installed properly they work very well.

The next step up is our LS4 add on cooler kit which uses a similar cooler as above but is a little smaller in size as it is intended to be plumped in line with the radiator. This kits features high quality stainless braided hoses and AN fittings throughout. A great addition to the radiator and helps drop trans temps down a good 20-40+ degrees over just the radiator cooler. Probably our most popular cooler option for the LS4 vehicles, just keep in mind you will still need a new radiator to use this. This kit is $224.95

The larger cooler option we have is a standalone TruCool Maxi cooler which is a long and narrow cooler that also features stainless braided hoses and AN fittings. This is a standalone kit that allows you to bypass the radiator and go straight to the transmission with the AN hoses. This kit is $274.95 and custom built per order as we have special fittings welded on the cooler for use with AN hoses.

Any of these are options you can decide on later since you will have several weeks before the transmission will be ready for you. If you have any questions about the coolers just let us know.

I'm thinking option #3!

So does anyone know if it is possible to fit the 4T80-E in our Impala's? I was looking into other model transmissions for our cars. I know that the 4T80-E weighs more but it is made with stronger internals. Not sure what the cost is for one but I do know they are just a bit more expensive. I'm in the same boat at 70K I'm having to replace the tranny on my SS. Which will be a good thing because I want to start upgrading my car to produce more power. Anyone have any additional feed back please post I want to learn, also is it possible to install the tranny with out taking the car to a shop. I'm pretty handy and have access to a lift?
