The transmission has been a little notchy since I bought it in October of 2000. I suspect one reason the owner sold the car was that he thought it was going out. He was running Redline, but I don't know if it was ATF or MTL.

I did a Service II immediately upon purpose at which time the 75W-90 synthetic was put in the tranny. My fault, I dropped it off with the car.

It got gradually notchier and harder to put in reverse in the morning. Once warmed up, it shifted "OK" but required a bit of a wait between gears. The lack of sudden change makes we think Redline MTL was in before.

Dow Corning's Molybdnum powder was all the rage on the Yahoo group a while back, so I decided to try it. Our transmissions are unusual in that they use Moly coated steel synchos instead of brass. The idea is to replace that worn off coating.

120 miles ago, I filled it with non-synthetic Dextron III with a tablespoon of MoS2 (Z Moly Powder. I got it at a local industrial supply store.

The car is shifting better and better. As I pulled out of the drive this morning I realized I didn't have to struggle to get it in gear for the first time since I bought it (unless the car was hot). Shifts are dramatically quicker and smoother. It is developing a nice tactile feel too. Makes you want to do it again...

I can't say enough about this fluid/powder combo. It is clearly the most cost effective thing I have done to the car.

I poured the powder right in the full container and shook well. I was suspicious that I couldn't see any difference in the plastic fill tube I was using. Then, near the end, it all came out at once. Great. I poured another third of a quart in the container, shook it up. That worked. I added another shot of powder, shook again and topped off the tranny.

I've been told this stuff stays in suspension very well, so I think the spoonful I added sank. There is soaked up fluid and stayed stuck in a lump. There was not enough mixing motion in the full container to disperse it. So, don't add it to a full container.
