Honestly the first time I can't really remember but it was about 20 something, the second time was about 40k.
the first time it blew though was after I got it back out of the shop, couldn't of been even a month, truthfully I think they pulled one over my eyes 'cause I think they didn't re-fill the fluid when it came out. It was nothing but body work, but a good bit of it. So in short the shop said it was warranty work so I got it done under warranty work, even at the time I thought it was funny though and still think so.
They should of checked the transmission and other major components, but they had it in the shop for over a month and I think they were having a lot of trouble getting it done on time so they over-looked something simple like the fluid.
The second time was really weird where I was in cruise control going down a bridge and all of a sudden it seemed to just down shift, I guess all the way to first and what do you know all the sudden Im running peak rpm's, really weird, I pulled over turned it off, then back on again it wouldn't get out of first gear. So I just fryed it down the road in first to get it to the gas station to park it and call a friend. I haven't had any problems since then or even any weird symptoms either. I would burn it out a lot down the road though once I got used to it. I can't roast 'em but I'll roll it all the way down the road till it catches second, then it'll gitty up. It used to be too fun not to do it. Still is, I guess im a little older and wiser now though. (maybe).
