GM Synchromesh Transmission Fluid: Part# 12345349
GM Synchromesh Transmission Fluid Friction Modified: Part #12377916

The stuff runs about $10-14 bucks a quart for the regular tranny fluid (Part# 12345349) and about $8-12 for the Friction Modified (Part #12377916) but figure $30-40 bucks is cheaper than a new ITR tranny ($1200+). Be carefull though if you decide to get this stuff, cause they have two different modified products... a "modifiER" and "modifiED"... you want the "modified" bottle that looks like a normal container that a quart of oil comes in...the "modifer" comes in a little small round bottle...so make sure you get the container that looks like the picture above... I baught 1 quart of the Friction Modified and 2 quarts of the regular Transmission Fluid for my car and ended up with about a 1/2 quart of the regular fluid first... put in the Friction Modified first before the regular fluid.

I previously was running Redline MTL in my tranny the past 3-4000 miles and decided to switch over to this stuff cause I didn't like the way 3rd into 4th felt. Nothing was grinding, just didn't feel as smooth as I'd expect it to be. Anyhow, they call this stuff Jesus Juice for your tranny so I thought to myself "what the hell, I'll give it a shot" and guess what... I've used in the other B-Series motors regular 10w30 before, Honda MTF and just previously a Redline product, now this GM Synchromesh and I'll tell yea what, I've never felt a honda tranny shift through gears so smoothly... It takes a few hundred miles for the stuff to start feeling like its doing anything (500-1000 miles) but wow... Sounds crazy to use a GM product on a honda, but I'd strongly recommend this product to anyone.. Supposively this stuff takes away synchro grinding, etc... after about 1500-2000 miles...

Here's the link to where I origionally read about this stuff... you folks might wanna try this stuff out sometime... works AWESOME!!!!
