Bill Evanoff at SCP says he's heard that the Art Carr kit is better for the AOD, & the Trans Go is better for the AOD E.
z90sc & I did mine on my '95 4R70W & had our share of problems. I had to lower the pan & VB 4 times before finally getting it working right this afternoon. Problem was that we had removed the O/D servo by mistake, & when we put it back in we didn't align the servo with the band. Not sure if your tranny is similar to mine on the inside since it's an AOD. As far as paying someone hourly to do it, after taking mine apart 4 times, I got it down to about 4 hours this afternoon. So I figure a pro might be able to do the whole thing in 4 or 5 hours? Just a guess. Neither of us had ever torn into a tranny before, & it was a good learning experience. Like Z said, follow the directions closely. If money's not an issue (& if you're not overly stubborn like I am!) then pay someone to do it. Especially if you're not experienced at working on cars in general. I'm glad I did it myself, though, & I'm really happy with the results.
Good luck!
