I use SP heavy in my now ITA spec SE-R race car. It is fantastic for weak sauce trannies like the one on the SE-R. I also warm the bottles in a bucket to make it pour better.

I want to try SP heavy in the Evo tranny next time. Right now I have 2 qts BG and one quart MT-90. It is hard to shifht when cold, but it is really good after the car warms up.

 

Great idea on warming up the fluid and I wish I thought of that before I poured it in which obviously took forever .

 

i have some stuff called synchromax by royal purple....havent had any problems yet. sounds like i should drain this stuff and try something else?!
