Well, it started to slip a long time ago.
Then, I don't know if you remember me talking about the rpms kinda "stairstepping" or "chugging" under throttle.
At some point during that time, I had my tranny rebuilt by my mechanic and had him install the ZZP shift kit.
Wish I would have had the cash to get a ZZP tranny but I was pushing it as it was.
