ive been reading posts all day about different tranny fluids. I was curious if anyone was still using the pennzoil/ gm syncroshift. If so what is the cange interval ,and the wear (hows it hold up). Most of the posts were dated. should it be used if the car is run hard on occasion?
I was going to run redline lightweight shockproof, but on the redline site it states(not recommended for most syncro-type transmissions) even though AMS recomends it. BG sycro is sold buschur racing. No wonder im confuse even 2 of the evo giants differ. I just want something that works and i can take my evo8 to the 1/4 mile with.

 

Well, no matter what opinion you state, 50 people are going to disagree.

I think the BG product is better than the GM product. I lost a transmission running the GM product. But, I suggest they are both passé, made for transmissions with weak syncros and Mitsu used to make nothing but.

If you value shifting over transmission life they may still be what you are looking for.

 

Quit using it back when the price went up. The stuff worked well when I could afford to swap it out at every oil change. Now, it costs as much (more locally) as the Amsoil I'm using, and the change intervals are L O N G with the Amsoil. However, the stuff IS notchy when temps drop below 50's on down.

 

Redline cocktail for me (2 MT-90 and 1 MTL mixed). Still shifts smooth even when below 0F during MN winters. Synchroshift/mesh does not have good sheer stability and doesn't provide the protection our transmissions need for long term durability.

 

Go to our reviews and ask some of those customers on how they like the AMSOIL 100% synthetic tranny fluid, being a synthetic it will hold to temp very well.

 

I just ordered my Redline fluid 2xMT_90 and 1xMTL. The tranny is a bit notchy going into third hopfully this will clear that issue up.

 

How long are the change interval with the amsoil? And to those using the redline are their any problems with the syncro or durability of the tranny?

 

I have been using the GM synchromesh for close to 3 years now and has shifted great the whole time, I change it every other oil change(so its in for 6k miles). never ran it longer cause everyone says it doesnt last long. But recently i have been looking into the amsoil cause its getting great reviews and its the proper weight and rating and offers better protection..

 

I've been using Synchromesh also and have not had a problem yet.

 

what about the OEM trans fluid, has anyone even consider that? My friend works at the mitsu dealership and i guess they get their trans fluid on big containers, and he told me next time you change ur trans fluid let me know and ill fill you up a container with the proper amount..

 

i like bg.. i beat the **** out of my car almost everyday or every other day and didnt have any proplems the fluid lasts longer than my clutch does

 

In the T-case I use Amsoil Severe duty SAE 250. For the tranny, I use Amsoil Synthetic GL-4 75w 90

 

ive just been using the oem fluids. changing out every 15k cuz the car is autoXed regularly. no issues as of yet, but im only at 60k.

 

double the ammount of the OEM, so if you change your OEM at 10k change the AMSOIL at 20k

the reason we do it this way because the user of the oil knows how hard they drive their car, therfore the drain intervals become sooner as you drive the car harder, with that being said some people might change their fluids every 1k or every 15k, because everyone drives their cars totally different.

 

Pennzoil Syncromesh for over 100k. I change it out every 6k or so. Still on the stock trans
