    Yes I tried searching, didn't find what I was looking for.

    I'm planning on changing out all the fluids on my 2006 2.7L 5 Speed 4x4 when the weather gets a little warmer and had a question about what brand of transmission fluid to use.

    In my old Jeeps I had to be careful what brand of fluid I used because of the brass synchro's in the trans. Wrong kind and they'd get eaten. The other problem I found when I switched was that once the weather got cold the fluid took forever to warm up and was like shifting through concrete.

    So my questions are what fluid are you guys in cold weather areas using? And do our transmissions have brass synchro's I should be worried about? Tried 2 or 3 different kinds in my Jeep, don't feel like doing that again, got expensive. Only want to have to do this once.

    Thanks

    Any 75W-90 GL4 would be best on a budget, but I spent a little more and went with Redline MT-90 which is GL4 for the brass synchros. It isn't the brand you need to be careful of but the weight and type such as 75W-90 and GL specs. Shifts in the cold got much easier for me. Most synthetics are more one and done solutions, but don't be worried about the brand as much. Change more often if you go with the regular stuff, but even that lasts a long time.

    I used the MT-90 in the Jeep and it was pretty good, also used Penzoil Syncromesh. The MT-90 was definitely better but a pain in the ass to get. I'm not worried about being on a budget, I just don't want to have to change good stuff after 6000 miles because trying to go into first gear feels like I'm going to break the shifter off in January.

    Do the transmissions not take atf now-a-days. Haven't used gear oil in a manual tranny in a couple decades. Made the mistake once of putting 90 in a t-5, had to disassemble it.

    This is a gear oil only transmission. BMW and some American cars take forms of ATF in manuals.

    I have always had to order MT-90 and it comes in the mail no problem. It takes about 2.3qts so you need 3 and a pump.

    Hmm.. looked around and couldn't easily find it. The 6 speed might take it. they added some several quarts of it to my engine repair bill, might have drained the transmission/transfer case.

    So I'm planning to (finally) change out the fluids on the truck this weekend and can't seem to find Valvoline full synthetic anywhere. All they have is dino oil. Only synthetic they seem to have is Mobil1 LS. Pretty sure the Mobil1 is GL-5 which I don't think I should be putting into the transmission. Any thoughts or experience? How the hell can it be so hard to find freakin gear oil?!?

    I have always had to purchase oils online. That way you get what you want and don't waste gas driving around trying to find what you want.

    I used Redline MT-90 when I did mine. It only helped a little in colder weather (25-35*F), but I'm happy to have a good synthetic in there nonetheless. The Redline website has a search for local retailers. There is one small shop about 40 miles from me.
