Buying a 7AT transmission 4-5 slipping

Wonka2581

Can't you buy a racing auto transmission for cheaper? I really don't know what brand of transmission it is.. But I think I remember reading somewhere that someone makes an aftermarket auto trans for our cars.

Could I get someone's opinion on this:

Will it fit? It's got a 90 day warranty. Can a regular transmission shop do the fluid swap or is it a dealer only thing?

It says the trans is from a 370z so it should be fine. I'm guessing you drive your car "spirited" which is why your transmission is going out. If that's the case then you should consider getting a built transmission. If you have 150k+ from normal driving then I'd say yeah, the used 21k transmission might not be a bad idea.

Would a regular shop have the equipment to do the transmission fluid change? A system capable of reading the transmission fluid temp. It looked all new stuff in there but I have to wait till the morning to ask them.

I'd think it depends on the shop but probably not. I believe the OTD price that I paid for a transmission flush through Nissan was about 200 bucks.

Thanks for the help brother.

I also got quoted 10k (from the dealership) for a new stock transmission and went with Level 10 last year. Best decision I ever made.

How long have you had it? Anything else you want to add about it would be much appreciated.

I have had it since September. I paid right under 5k. They have you send in your transmission and completely rebuild it. Shipping takes 2-3 days one way depending on where you live, takes them right at 3 days to rebuild it and then they send it back. My car was down a total of 8 days. It is built to withstand either 700 hp or like JWillis 1000 hp which obviously cost a little more. I can tell a noticeable difference in how fast and firm it shifts. Much better deal than just going back with the stock transmission that cost more and could end up breaking again.

4-5 gear slipping is mainly the valve body problem. I helped 3 people locally to order the valve body upgrade from Level Ten already.

I second everyone who stated Level 10. These guys do great transmission work for our 5A/T and 7A/T platforms. I've been tracking their "bulletproof" transmission for a while now with 500awhp without any problems.

I must confess it was my mistake and not the manufacturers. The car was on jack stands and I was testing for exhaust rattle by revving the engine in drive. I had my hand on the brake pretty firm and I put in park before the revs dropped all the way down and the tranny (parking mechanism?) went *click click click* and the issue has been getting worse since then. This happened at 30k I think and am now at 89k
