Opinions on 4 speed with OD

Tremecs weren't the greatest shifting. Notchy and weren't able to power shift without grinding or not going into gear at all. I had the first one in a Duster in 2000 then 2002 in a B body. I did have to do some surgery to install them,not much just had to remove a few bosses in the case to clear the floor.Now things may be different 20+ years later.Both cars I had to have driveshafts made but can't remember if I had too or if I wanted too.

The new TKX is supposed to be the bomb compared to the old TKO's like you had. And the old TKO swaps usually had a bad driveshaft angle that could cause problems too.

I can see your point though, if you are getting on it and the trans won't shift, makes it hard to overcome the value of the extra gear.

I still look at pictures of your Duster. Sweet car. Too bad the trans detracted from the overall build.
