If you would care to look at the top of this page you will find an advert for RBT Transmissions, click on that advert & go to the FAQ section...Frequently asked Questions. There you will find on the 2nd FAQ the info you require as to how many quarts each model takes ( just make sure your talking the same lingo... Us Quarts versus English Quarts etc etc........ also recommendations on grades of oil to use....

I suspect this is what you want. Not synchromesh. Note this gear lube is rated for both GL4 and GL5 by using less corrosive addatives. It is around 75W-90 as I recall and it is a synthetic. About $20 a quart. Perhaps someone can chime in regarding some conventional non syn GL4 gear oil. Seems most of what is stocked at the local parts stores is GL5, which we don't want.

I'm looking for info on what type of gearbox oil and how much.
I have looked through these threads and have pulled up the RBT FAQ section.
I have an RBT-5 DS-25/2, mounted in a SPF GT40, my question is: are my output flanges above the input shaft?
2.5 liters of oil
****************
Or are the output flanges below the input shaft?
3.5 liters of oil
Additionally, any recommendations on the type of gearbox oil I should use.
Thanks!

It's important to use GL-4 lube and not just throw in anything you happen to have lying around. Even the super-duper double-throwdown excellent gear lubes, which are designed to work in conventional transmissions and/or rear ends, aren't appropriate for a ZF.
Sta-Lube markets an 85W90 GL-4 lube, which is available at NAPA stores in one-gallon jugs.
This is what I use in my Pantera, and it works perfectly. No gimmicks.
It's important to change it every 2-3 years even if the car has received only light usage. Moisture and condensation can build up which can wreak havoc inside the gearbox. Some people change their engine oil religiously and NEVER change their gearbox oil; Lloyd Butfoy told me a gearbox came in that had been running the same oil for 30 years! It stunk up the joint so badly that they couldn't even stay in the building with it!
The gearbox was trashed inside BTW....

Old thread but related question: anyone have blow-by issues with 2.66 qts (2.5 qts recommended) My small breather filter is located about 12" away and 4" above the trans (just a line & filter, no catch can) and get excessive blow-by exiting the breather filter. We're only talking 2/3 of a cup over the recommend level but would that be enough to cause oil exiting the breather?
Also, any opinions on Amsoil MTG 75w90 (GL-4) for a ZF?

When I first got my CAV it had some drips from the right out-put seal. I needed to check fluid levels. I did a search and got multiple different answers. I called RBT and got transferred to Lloyd the owner of RBT. Lloyd said to use "NO" additives at all! Amsoil is "Snake oil" IMO, so beware.......and do what the manufacture says. (3 qts total without any cooler or lines)

Rich, I've had great results with Amsoil engine and trans oil in other applications so I drink their cool-aid! I choose the MTG because it's a GL4 and not the additives their GL5 Sever Gear contains. I think I'll also try it my G50 as well.
On the other issue of blow-by I discovered this interesting item adapted to my breather fitting yet I still had excessive blow-by. Again would 2/3 cup over the recommended 2.5 qts produce blow-by?
