If I'm correct, if the shift timing isn't setup properly then 1-2 can bind when shifting. I THINK. I'm not sure though. Sounds like something in the valve body definitely isn't setup correctly though.
You are thinking of 2-3 shift. The 1-2 shift goes from having the rear clutch applied to rear clutch and front band applied. Thus, there shouldn't be an overlap there.If I'm correct, if the shift timing isn't setup properly then 1-2 can bind when shifting. I THINK. I'm not sure though.

I did get a chance to remove the old bearing in the pump housing that supports the shafts. I also put on new seal rings. A couple stock ones, and a couple others that Transgo provided with their shift kit. So I guess I better hope I didn't damage them during the install or when I put the TC in. :lol3:There are a bunch of rebuilders that say a complete rebuild on the RE transmissions includes the governor solenoid and transducer.
As to the problem, I'd look at the front band adjustment. After that, I'd have to see exactly what was done to determine if the shift kit changed things or not. The spring in the rear servo versus the different hole sizes shouldn't have anything to do with forward gears, since the rear band is only used in reverse and manual low.
Another possible problem with the shift could be a broken seal ring, or a bad bushing on the pump support for the shafts. If you leave out a torrington bearing, this could allow the front drum to slide, causing the seal rings to be ineffective. That said, I'd stick with the front band and electronic inputs for now.
