I had to notch out quite a bit of the adapter so that I could get it to clear the headers, probably a good 2 square inches of material. I also had to remove material from around one of the bolt holes on the actual transmission bellhousing. Even so, I had to stretch the headers out, completely remake the y-pipe, and most of the exhaust as well. After finally working the tranny in there, the catalytic converter was resting against the bellhousing. I had already overheated three of the stock trannies, so for heat issues, I chose to relocate the catalytic converter. The only good place to do that is where the muffler is, so I removed the muffler and put an aftermarket cat in its location. This also pretty much meant that I had to replace the majority of length from the exhaust pipe. The TV cable, as mentioned above, is about a foot and a half too short. I bought one for a 95 chevy pickup, and welded a little ball on the end of the cord. Which cost 16.99 versus the 109.99 that Bow Tie Overdrives wants. I called Bow Tie Overdrives, and they assured me that it would fit, because 'it worked on the bench.' They pretty much told me I was doing it wrong, as were the mechanics that were working on it. Their customer service is not the best. My mechanic called them about the freeze plugs being loose prior to install, and Bow Tie Overdrives pretty much told them that there was no way that it left their yard that way, and that it must have been the customer. Not to mention that fact that the first tranny they sent me was a 2wd version, and I had to get them to pick up the one they sent and install a new output shaft. Actually, they initially wanted me to do the work. They said that they would ship the output shaft and I could send them the old one when I got it out. Naturally, I told them that they were going to do the work, because if I knew how to build a tranny I would not have ordered one from them. Anyway, since I was installing an atlas at the same time, I also needed a new crossmember, tranny skid plate, and driveshaft work. There were other issues as well, such as the bellhousing dustcover from advanced adapters. This piece falls about an inch short of covering the gap. I'm sure there were more, I just can't hink of them at the moment.
