1st to 2nd slipping/quick

Trans-go changed things in the TF-2 kit just slightly about a year or so ago. Most likely that's the kit you have since you say it was about a year ago when yours was done. Hopefully the band adjustment takes care of it but if it gets to the point of you having to drop the valve body and check things over and you find the pressure regulator spring is just 1 spring (that's one of the changes, they now give you a booster spring that fits inside of your existing spring) it's the older version of the kit and I have the instructions for it scanned into my puter so if you need them pm me with your e-mail address and I'll send them to you. I also have exploded views of the valve body from different sides I can send you that shows how each valve and springs go in if you need it to double check things to make sure he put it all together right.

BTW: I like the way your adjusting the front band also. Like you I can get things real tight with even a short wrench so I never liked that way of adjusting the band. If your not sure what front band lever ratio is in the trans. torque it to 72 in. lbs. and back it off 2-1/4 turns. That's a happy medium that works well with most any lever.
