Default Looking for replacement Trans

I really need to swap out my transmission in my 69', its basically a junk 3-speed place holder not original to the car.

I want to upgrade to one of 2 different trans:

1. Stay classic w/ a 4-speed
2. Step into a more modern 6-speed

Anyone have recommendations for either I'd really appreciate it; thanks in advance. And feel free to sway my thinking one way or the other.

I have installed the Richmond 6 speed I think it is a good trans. but have not had my car on the road for alot of miles. I also put 3.70s in and the car does do about 2500 at 70. If you check my page there are pics of the install but i did it with the body off. I think any 6 speed you do, you will have to pull the motor or take out the cross member and both have to alter the cross member trans mount. I would do some searches because I have seen many variations of trans cross member adaptations.

The TKO 5 speed is an easy trans to install and gives you an overdrive for nice highway cruising and good perfromance in the first 4 gears. I had one for years and thought it was great. I have since gone to a T56 from an 06 GTO. Better transmission and double overdrive but it is no bolt in for sure. This took quite a bit of work. it has been worth it and I can cruise at 70+ mph at 2000 rpm. The 4 speed is old school with no overdrive.

I was flipping through the may 2011 issue of car craft and they did a product review of new Keisler 5-speed transmission that they basically said is better than the Tremec TKO; does anyone have experience with this trans yet? If so, please share

What engine and rear end ratio?
If it's a small block with 3.3-3.08 a TKO, Keisler, etc with a 0.6x OD will be too much gear. Costwise, a 4 Muncie would be a good choice.
I went with the richmond 6 speed with a 0.76 OD and 3.08 rear.

It pretty much looks like I narrowed it down to a keisler 5 speed thats gonna go in pretty straight forward and ive got some pretty good feedback from people i know and trust.

Thanks so much for the feedback, I really can't get enough of this forum

You need to know your rear end gearing before ordering the Keisler TKO. The TKO 500 and TKO 600 both work but have different gearing to match your rear end gear ratio better.
