The days of needing a specialized transmission stop leak formula are over. With modern chemical technology advancements, it’s now possible to have a transmission treatment that handles any type of transmission. This type of product is not easy to engineer. It requires years of experience, and a ridiculous amount of lab time. It requires a deep understanding of transmission technology, common problems, and what root causes lie behind these problems. We did the research. We put the time in. The result is Bar’s Leaks Super Transmission Fix, the only transmission treatment that handles just about any type of transmission If you have a transmission that’s suffering from leaks, slipping, jerking, hard shifting, shudder or just plain poor shift feel, Bar’s Leaks Super Transmission Fix is the only bottle you need to optimize transmission performance.

Hello, I just wanted to write and tell you how thankful I am for your product! I have a 07' Pontiac Grand Prix and have been having issues with the transmission slipping for some time now. Unfortunately from online reviews I went with Lucas' transmission fix. That didn't do a thing! So yesterday I decided on your Super Transmission fix & noticed results INSTANTLY! I couldn't believe it! I just got back from dropping my son off at school and am still amazed how there's no slipping or lagging like before. Wish I would have went with your product a year ago! If you need any reviews or anything from me please let me know. I'm an actual customer who's very happy! Being a single dad raising my son full time, I was worried about paying for a new transmission. Now I can rest easy that this will hold me over for awhile until I can afford a new vehicle. So thank you again!!!
