I noticed that GM offers two different kinds of the Syncromesh. I was wondering if anyone has tried both kinds yet? I use to run the cheaper GM synoromesh in my car. It was great for the first 2000 miles or so then I started having shifting problems again. I haven't tried the more expensive of the two yet. If anyone has tried it please give us some feedback on it.

Thanks,
Barry

 

Not sure what the difference might be, but the stuff I am runnung is numbered 1#12345349 on the bottle and is a partial synthetic fluid that is amber in color.

 

Thanks for the part number. I will have to check it out.
