I just changed the fluid in the tranny to amsoil and holy crap did it make a huge difference. I can't believe, how smooth the car shifts into gear now. I recommend this to everyone with a 6MT car.

 

Really? I have alwayse been wanting to do that but just never had the chance. I might do it when this summer school class ends. Did u change it yourself?

 

What transmission oil (part number or other particular reference) you used?

Thanks!

did it myself, took about 2o mins, about the same as changing you oil

changed the tranny fluid in 20 minutes or the differential fluid?

 

...

 

Even when cold? The syn I have in right now only shifts good when hot.

also, what year Z?

 

Where do you live and what weight are you using?

 

South Florida...The SAE weight of the MTL-P, 75w85, is identical to the stock dino, but from a bit if reading on bobistheoilguy.com it seems these numbers are more significant:

Specialty Formulations MTL-P
K. Viscosity@100C: 11.3 cSt
K. Viscosity@40C: 73.2
Pour Point: -47 F
Specific Gravity: 0.87
Viscosity Index: 141

 

I recently went to:
Manual Transmission -
Redline
2 qts. MTL 70w80 (GL-4)
2 qts. MT-90 75w90 (GL-4)

I haven't had a chance to test drive it. I've heard nothing but great results though...

 

I just switched to 1 qt MTL, 3 qts MT-90 and its amazing how much of a difference it made. It is so much smoother now.

 

amsoil huh? I think i know what Im doing on saturday. lol Wait, i just visited the site, can I just purchase this in autozone or somewhere or do i have to order online? thanx

 

Don't count on it. You'll have to go to an authorized dealer or get it online.

 

That's what I'm hoping. Mine was starting to get alittle rough on the shifting. I won't know any results until I finish the radiator flush, then I can drop the car and test drive it.

 

Thats my next change, I plan on going Amsoil. I have Redline Synthetic Mix right now and its really good, car shifts smooth. Curious to see how Amsoil will perform on my car.

 

+1 I have Redline in the tranny now but I have Amsoil sitting in the garage now waiting to be put in.

 

Even when cold?

 

anyone using RP?

 

About when did you guys decide to change yours? Im at 26k right now and am wondering if I should do it soon.

 

Last time I checked the poll, RP was winning:
