Def. not easier than doing the engine oil unless you have a hoist. Draining the tranny is easier but refilling and having to use a pump is far more work and time consuming than pouring in the crankcase oil from above.

 

how many quarts of differential fluid should i buy?

 

1 1/2 if I remember correctly. But just buy 2. Typically when you fill the diff, and it starts pouring out of the side, you know u've filled it enough.



As for tranny fluid, definitly redline MTL or Mt-90 both will work.

 

Is synchromesh bad for these trannys?

 

Our diff does not require a additive. Only GM diffs do. Please do not use one.

 

how about for the diff? also from Amsoil, it's 80W-90 and GL-5.

i run redline MT-90 in my transmission and redline 75w-90 in my diff

 

Just a little confused based off of all the responses so I have a quick question. I want to change my tranny, differential, and brake fluid and based of the responses this is what I have gathered; if I'm wrong please correct. I have an 04 G coupe 6MT and for my tranny fluid I should probably use Amsoil MT90 (75W/90) full synthetic, for the differential BG Ultra Guard (75w140) or if someone recommends something else please advise. Lastly I'd like to change the break fluid and from what I've gathered ATE Super Blue seems to be the best recommended. If anyone has any other suggestions I'm all ears. I have roughly 95K on my G and was also wondering what else I should have done to keep it running smooth. Thanks

 

I run MT90 and MTL 50/50 in my tranny and 75w90 in my rear diff. After the last track day and how hot my diff got I am trying to decide if building a diff cooler is worth it and/or maybe changing to 75w140.

I'm going to do another flush with Redline MT90 and MTL 50/50 and the heavy shockproof in the rear diff. I'm also building a diff cooler at the same time.
