trans ratios
About what RPM's are you guys running at 70 mph in Fifth? I run about 2850. I am trying to figure out my gear ratios and final drive ratio of my RBT ZF. chuck

The ZF gear ratios are on a plate attached to the side of the box toward the rear. Even has the reverse ratio but I've never been worried about what revs I'm doing or what speed while reversing.

Re: trans ratios
Ok, I have a .704 5th and 4.22:1 C&P and I see about 2800 revs at 60mph/100kph.

Re: trans ratios
Chuck,

Here is a picture of the plate location on mine...I plan to shoot a closer picture of it next week to record the gear ratios.
