Been wondering how the 8At transmissions been holding up in general to modding.

In my search on the forum, i havent seen any major problems with modded cars having any issues with the trans.

I have only heard of one incident where a friend had both engine and transmission failure.
Only mod was the BMW Performance kit.
New engine and Transmission was covered by BMW 95%.

I've had no problem whatsoever.

Depends on the use case. If you're doing less than 20 second pulls with substantial powertrain modifications, you may be within the envelope.

However, I would imagine that if you're actually tracking the car and have substantial powertrain modifications, you could easily exceed the heat exchanger's capabilities on the ZF 8HP.

Fair enough.

Makes sense.. Seems to be a solid trans with basic bolt on from what i could find.

I forgot to mention that my car has a +100 hp / +200Nm more than the one mentioned. We both track and USE the car fully more or less on a daily base.

The transmission isn't week on these cars.

(I run max. 18,8 psi at the the moment, daily).
