I had this issue with my trans as well...don't remember what the PO said he had put in it but it felt really notchy even when warmed up. Now running Mitsubishi Diaqueen in it and it's like buttah.

This for me. But mine is daily and was hard shifting with RL. Did this when I replaced the engine 2 years ago and all is still good.

I'll try one day on track with the amsoil and perhaps it will soak in but if it still sucks Ill try the "unicorn jizz"

However, RL sucks, AMSoil MTG is the way to go. Blackstone told me that two season of track time (~25-30 hours per season) didn't require a change and I should keep going. I had a slightly sticky synchro in 5th, the change seems to have fixed it. Savington and I sustain 300*f+ trans oil temps.

Yesterday I bought 3 quarts of AMSoil 75W90 GL-4, because here in Canada, it's hard to put the hand on the good products....

Should I'll be fine using it or should I bring it back and get something else?

Ok so should i swap out my new Redline for Motorcraft Unicorn Jizz or for Amsoil MTG?

What about diffs? I put Redline in that, too.

I have run both light and heavy shock proof as well as Redline MT90.
My experiance is it provided no added durability for the transmission got real hot and shifted poorly hot or cold.

Amsoil MTG seems to be better in every measurable way for mazda 5 or 6 speed.

at first the amsoil did not seem any better, after some street miles and a session on the track, the car seems to shift fine now. I guess the oil had to get hot and mesh with the gears or something. it may not be 100% perfect but so far it seems much better and no longer something I consider a problem
