Late 1-2 shift

Just had a transgo T-FOD Diesel kit installed by a reputable shop. Tranny shifted and held fine before the install with no other problems. Just picked my truck up and it shifts waaaay late from 1st to 2nd when cold like 2600-2700 rpm. But it shifts awesome once the tranny warms up to 140+. At first I thought the tv cable was way out of adjustment but ruled that out once the tranny warmed up. Called the shop and he said it could be the gov pressure solenoid which sounds plausible with what I do know. So what do you guys think? Is there anything I can try adjustment wise right now to see if anything changes?
Thanks!

Late 1-2 shift

Well I guess I could bump this one back up with a solution, some playing around with the tv cable got me the results I was looking for. Shifts at about 1300 rpm under light throttle. Wot shift points are about the same as they were before which is fine with me.

if you put in the upgraded throttle valve spring it shifts way later. i installed it at first, didnt like it. put the stock one back in and love it. esp when you have more power, you want it to shift faster to be quicker.
