1st to 2nd slipping/quick

adjusted the front band,it's a little better,but still not right.Talked to Transgo,he said till I put a pressure gauge on it no sense talking about it,which I agree with.Wish I knew someone close to me that I could borrow one from.Found them online for 30-50 bucks,just have to add it to tools I've bought that I've only used once.LOL
