Another good choice is GM's Syncromesh....SHSSS don't tell anyb ody you have GM fluid in your tranny. But all serious i know alot of people that really like it and use it in there stangs. and it won't cost a ton like Royal Purple.
any ideas for an automatic? I'm probably gonna flush my system cuz i've got a small radiator leak and the tranny fluids mixing with the coolant. Just wondering if the same stuff (royal purple) or something else would be good.
The quart bottle of the Syncrhomax is about $8. How many quarts you need, that's a different question! Price shouldn't be too big of a deal since you don't have to change the fluid that often.
I changed my transmission fluid a month ago useing Royal Purple
and now it shifts alot smoother and it makes less noise than it did
before.Royal Purple is great stuff and lots of people are running it.
