TriboTEX Transmission - Differential Formula
Put TriboTex differential formula in maunal transmission Subaru Impreza that has a bearing whine that changes pitch with vehicle speed. There was no change in 15 minutes, or after 100 Miles, or even now at 1000 miles. Bearings will make this noise when the races get slightly pitted. TriboTex did not seem to fill in any of these areas to smooth it out.
I have a 3rd gear that is grinding when I down shift. This didn’t fix that completely but it makes it smoother but I’m not sure if it’s the TriboTEX or the lower viscosity oil that I switched to, which is conventional. Therefore this product should be cheaper as a generic friction modifier. It says it will repair bearings which isn’t the same as a synchronizer I suppose.
I really don't know yet. Just had TriboTex put in my Tranny and differential yesterday. I did so because last year I had a riding mower that was really sick and put a tube of Tribotex in that and saw tremendous improvement. I put the product in my 2013 Silverado to help it last forever, currently has 60K miles.
Not sure I'll be able to give Tribotex a fair review on the 2013 Silverado as I did not have a problem and hope never to have a problem. Perhaps after 500K miles I can report back. The product is rather expensive however perhaps it is expensive to produce.
I have an 08 duramax ! After ordering and installing tribotex diesel truck engine additive, my wife said what did you do to the engine cause it’s quieter. So I told her . I then ordered power steering , front differential , rear differential , transmission, transfer case. The truck has 180,000 miles and is quieter when driving it down the road . It took more than 100 miles to be quieter .
