  • Great in my Land Cruiser trans
I use this in the H55F in my Land Cruiser. Excellent, dependable fully synthetic MTM fluid that is safe with the yellow metal synchros in my trans. It's a confusingly named product - it says SAE 50 but this is equivalent to a heavy 90 weight gear lube. I don't know why this information is so hard to find, it's like they're being intentionally confusing. Do not use it in differentials - just for manual transmissions. Not cheap but should last a long, looonng time. I only use Mobil 1 full synthetic in my Cruiser, for every lubrication need. ... show more

  • G56, changed my mind
I ran the Mobil delvac 50 in my G56 for 10k miles, them switched to Amsoil MTF 5w-30. The Mobil is a pretty good transmission fluid, but it causes the transmission to shift slow and clunky. And if it's below freezing, the truck is basically undrivable locking out some gears and grinding others. After switching to the Amsoil, the gears line up smoothly the way a normal car drives, even in cold weather. It's very close to the Mobil in quiting down the gear rattle. I'm not an Amoil fanboy. These are just my personal experiences with my Ram truck. I'm keeping my five star review up because I think the Mobil is a good oil, just in a tractor trailer, not the G56 ... show more

  • Arrived with no issues
I've bought four of these jugs between two orders, all arrived with no issues. One of them did come in a clear plastic bag with tape around the lid saying something about spill protection, but I didn't see any leaks and the seal was still intact under the lid, which wasn't opened. Had to buy four jugs to use in two trucks that have G56 trans with Valair single and triple disks. 7qts each ... show more

  • Best oil yet for a G56 transmission
I was having a lot of noise and vibration after a recent transmission oil change using ATF4 as Dodge recommend for the G56 transmission. Did some research on line to find this oil is recommended by Mercedes who makes the transmission. First test drive after changing the oil and this stuff is awesome in a G56 manual transmission. Smooth, quiet, and easy to shift! ... show more

  • this is way better than anything else
I have read alot of forums about this stuff for dodge G56 Transmissions, this is way better than anything else. Poured it in and drove 2500 miles in a rebuilt trans and ran smooth. No gear issues or shifting, its a little stiff in the cold but I don't beat on the trans so it's fine for me. Def way better than oem transfluid. No gear rolling noise or whine. Def gonna buy more for trans fluid change. ... show more

  • Made a huge Difference
Went with this after reading comments from various parties on line about replacing ATF+4 in my manual transmission with this. I tow 10K pounds almost weekly in the summer. While it is debatable which brands is best and all that, at least in my case this stuff is great compared to ATF+4
