I live in NW INdiana ad don't drive the car at all in the winter. Can anyone recommend the best oil to use for the 833 manual trans? I'd also like to know how much to ut in. Thank u

Passon Performance makes the best fluid and I beleive it is 4 quarts.

Its slightly under 4 quarts. About 3.75.

Got it...any particular weight that works best for the 833? Should I shy away from synthetics?? I love using Royal Purple in almost all of my cars including my 2009 Ram. Is this a good idea?

Some people like synthetics in an 833 some don't. Redline is good.
1 BIG point!!!! Do NOT run a GL-5 in it. You need a GL-4 which can be difficult to find. (especially non-synthetic) THe GL-5's have extreme pressure additives (they're for rears) that are not friendly to your synchros.
75-90 works,

Thank u Pac....will look for it!!

75W-90 is a good choice and if you have an older tranny use 1 qt of Lucas oil additive. It helped quiet my 35 year old never been rebuilt tranny in my previous Duster 340-4spd car on WOT up shifts.

If you want it to shift at rpm just run atf in it.

I have been using RedLine MTL (Manual Trans Lube) and I am happy with it. Check out RedLines web page for more info:

i use Passon's fluid, its good but thin and may result in more trans noise than a 80/90

I tried ATF and then Passion Lube in mine. Never did work right. Would grind going into the gears all the time with those two different lubes.

I put 85-140 in there and it works good. I was told my box wss junk on here before the 85-140 went in.

It certainly isn't cherry but it works good and hasn't had to be torn down yet. Had 102K on it when IO began this exercise and now has close to 108K after this summer with the heavy stuff.
