My dealer will put XL-18 to my transmission today (2011 GT). I hope that I will get my car back today...
Are you over 60K on the miles? I ask because I've seen many folks here not realize the power train warranty is 60K and they think the power train warranty is the same as the 36K bumper to bumper warranty.I can't find XL-18 at any of my dealers. So since my car was bought used with no warranty, I dicided to go the motorkote route, and I must admit it works great. This is also a friction reducer which from all the rading I've done is what XL-18 is. If my car was under warranty i would not have tried such a venture, but to be honest keep in mind anything that happens is on me anyhow!!!! But It works, still not as smooth as my t56 on my last ZO6 but a huge improvement from the clunky hard shifts I was experiancing.clap4.gif
With this product, do you drain and replace all the gear oil, or is this used as an additive?I have Royal Purple SyncroMax in my 15 since about 2.5k miles, have 21k now.
It made a big difference in the smoothness of the shifting. Still a little notchy going into 2nd when its cold (below 30F) until the tranny warms up.
