ZF automatic questions

Postby Artiz1 » Tue Feb 09, 2016 9:20 pm

How much torque and powere are the ZF automatics capable of withstand safely?
I know they were fitted to various french and german cars, even the same transmissions (just different housings) were used on the rear wheel driven BMs and Mercs. So in theory these gearboxes should be safe to use up to about 250 bhp... This is my though. But perhaps there are some experts out there that can confirm this with some scientific data etc?
Asking because I yet don't know what to do next with mi car - use the existing 12V engine or go for the 2.0 V6 turbo, which in that case would not be so stock anymore...

I don't know but had some email correspondence in the past with Mr. Tibor Bäcker at ZF. If you put a full stop between his first and last name and then @zf.com you have his email address. He was quite helpful to me.

Thanks for the contact. I first have send an email via ZF website contact frorm. I'll see if I get a reply. If not, I'll try your contact.
But perhaps there is anyone who knows any rough figures?

Today, I finally got an official answer from ZF, which I think is worth posting for future reference:

"Dear Mr. xxx,

the 4HP18 QE has a torque capacity of about 340 Nm and this is the critical characteristic for an automatic transmission.
The maximum engine rev is at about 6200 rpm. You wouldn’t be able anyway to bring more than 300 Nm even on a dry
street surface with a front wheel driven without traction controll.
For an oil change you can use Dexron III oil spec and a filter can be ordered from the ZF Service organisation or ZF partners.

Best regards"

My Super's 3.0L 12V is producing 132kW and 255Nm. So even if I play a little bit more with it, I should be fine :)

:shock:

The Alfa 24V revs up to 6.500 rpm at maximum speed. Good to know that even the transmission of the Automatic 24V is not reliable on permanent German Autobahn run. Until yet I had already 2 24V engines collopsed at 240 km/h on the way through German - I guess beacuse the engines revs permananetly higher as in 5th gear with the manual.
