What Gear oil to use in the trans 2000 jetta tdi? Thinking I should change at 200,000
Is this synthetic? Or more importantly, do they make a synth and non syn version of G70 like they did with G52?dieseldorf said:Rumor has it that the new G70 from VAG is top notch stuff!
What was their reasoning, was it GL-5?Mbmaring said:I see most everyone agrees do not use mobil one in a 5 speed transaxle
MTL has been great with fixing frozen gears in the morning. Previously had what I think was the original gear oil, which took about 5 minutes in the morning to warm up. I haven't tried anything else in the TDI yet.Powder Hound said:I vote for Redline MTL in a gear box. If an auto-slush box, I will pray for you.
Yes mobil 1 75w90 is GL-5. It also has some spec "MT-1" for manual transmissions but I really dont think its meant for a GL-4 replacement, and I would not suggest it. Works great in RWD rear ends though!Bob_Fout said:What was their reasoning, was it GL-5?
I heard the same from Growler on another forum. How is it in cold climates?dieseldorf said:Rumor has it that the new G70 from VAG is top notch stuff!
Some claim a mix should be used ot MTL and MT90 but I disagree, MTL has worked great for me in the cold and extreme hot. I will be changing it within a year and sending it to the lab for analysis.eats1963 said:I have to agree about the MT-90. I changed mine for the first time last fall, and during this extremely cold winter, it was VERY difficult to shift until everything warmed up. I will definitely be changing my fluid again before next winter.
+1 on the Redline MTL. Fixed my 2nd gear grinding and brought the trans to like new... Stock fluid made it worse after the change...eric_x said:MTL has been great with fixing frozen gears in the morning.

__. Last summer, I had my 5th gear set switched out for a .658 ratio gear. The installer drained the VW lube and refilled with Redline. Within 4 months, it started "popping out of 5th" but it's clear (looking at the damage) that the lube had nothing to do with the failure.Revolutionary_mind said:Some claim a mix should be used ot MTL and MT90 but I disagree, MTL has worked great for me in the cold and extreme hot.

G70.. is there only 1 version? Is it synthetic?
__. Got the info. It was the installation and not the lube.rez311 said:I doubt it's related. Maybe the gear was installed wrong.
The only problem with this is GL5 works great with new transmissions. It's complete crap transmission fluid when the transmission has too many miles on it. I was about to junk my transmission until I switched over to the Redline stuff and have gotten another 50k+ out of my transmission. The thicker fluid compensates for the worn parts, not to mention that Redline has awesome products.TooSlick said:The Amaoil GL-4 rated, 75w-90 is formulated significantly thinner that their severe gear. The GL-4 product is also non-corrosive to "yellow metals" at elevated temps & is the product to use. The 75w-90 Amsoil Severe Gear is a HD synthetic gear lube for differential use. It's excellent for heavily loaded diesel pickup axles that see heavy towing loads. But I would not use it for a manual transmission unless a GL-5 is required - something like a Subaru for example...
I've been using Amsoil since 1978 and have a fair amount of experience with their various fluids....
