Keisler SS700 gearbox.

[Jack Zupan]

I have a TKO II in my car with 0.84:1 overdrive. The reason I didn't go with the 0.64:1 ratio was because a number of people unhappy with it simply because there was such a huge drop from 4th which is 1:1 to 0.64:1 that it felt funny. I have been happy with what I have.

Regarding Kiesler I would suggest you cruise some of the Mopar sites. While they have some supporters, most folks are unhappy with them. They advertise a bolt in installation and it is anything but from what I read. You have to cut the trans tunnel and weld in a new piece for one thing. Most people who have decent cars are not willing to do that. There is one guy who just finished putting a SS 700 in a B-Body and it took a lot of fabrication. Luckily the guy was experienced and had the equipment and skill to do it.

The other knock on them is that their customer service is poor. Given your location that could be a big issue.

To be clear I don't have first hand experience with Kiesler but I am on a number of Mopar sites daily and that is what I picked up. Try doing a search on moparts.com or forbbodiesonly.com and see what you can find.
