Someone told me if I use new synthetic transmission oil in my teener, I might get seal leaks because it is thinner than the recommended 90 oil.
Any thoughts on this? |

Dont even bother with it. My trans shifted rougher with synthetic. I swapped back to conventional 100 miles later.

The PO of my car put fresh swepco in my car just before selling it to me. My trans is probably very typical of the semi-tired trans that (at a minimum) could use new 1st and 2nd gear synchros. After replacing the shifter bushings, adjusting the linkage and the clutch and still not being happy with the way it was shifting I decided to try dino lube. While I'll promise you it is still a semi-tired trans that is not the best shifter, it definitely and noticeably shifts better with the dino lube. |

I was under the impression that swepco is a synthetic. Now it appears that it is not? Is that correct? If so I mis-stated my experience - car came with swepco, shifts better with the cheap stuff. |
