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?

I got my engine resealed last summer. They also replaced all the shifter bushings too. My mechanic said he replaced the tranny oil with new syn oil. He said it was the best. Was he ever wrong! Started getting leaks at shaft seal plus one of the CV seals. I used a piece of cardboard under the car to monitor the leaks. Yesterday, I replaced the oil with Valvoline Dino oil. I placed a new piece of cardboard under the teener and this morning it was completely spot free! Better is not always better! (IMG:style_emoticons/default/beerchug.gif)
