Thoughts on a 230 trans into a 240D

Was wondering if anyone has any experience with this. Its presented itself as an attractive option to my transmission woes. Donor car is a '75 and should be a 722.110. My car is the 722.108. The cars are essentially the same other than the engines. My main concern is how much the horsepower and torque differences will affect how it drives. Main thing is its known to be good. Car just rusted out.
Thanks for the insight.

Drop Frank R. a line. I'm pretty sure he knows what you'd need to swap in regards to valve bodies, use of modulator vs. Bowden cable, etc.

Starters are on the right side for both.
The shift points of the .110 will be a bit higher that those of the .108.
The vacuum modulator of the .110 will have to be replaced with the manually adjusted modulator of the .108.

I looked at the shift points in the technical data manual between the two. At lower speeds it doesn't look like it's as much an issue but under full throttle and for kick-down there is quite a variance. 3-4 at full throttle is 58 mph vs 70.

i put a diesel tranny in a 280. It worked fine but you had to let the gas off briefly to get it to shift at an appropriate if you were hustling it a bit.

I'd think this would be about the same.

My set of gauges are coming today. Maybe Iíll get lucky and can figure something out and not have to do this swap. I typically donít like to deviate from stock setups to be honest. Itís just that I can get the 230 trans for a bargain and get the car back on the road.
