Adding one more post. The 1-2 shift is a little slow but I'm happy with it. We are noticing that the 2-3 shift is a little delayed. Very little. The mechanic who worked on the car for the previous owner, told me he had adjusted the modulator valve to try to fix the 2-3 and 3-4 flare. So the modulator is now out of adjustment. It will probably be cheaper to put a new modulator in ($35) then to get the dealer to adjust it. I'll look onto that. Before I do that I'll try adjusting it, nothing to lose!

Also I added 2 cans of R12 to the AC. I could not find any leak in the system. I have a sniffer and tried for quite some time. So I'm hoping the AC problem was just years of a slow leak. I will put some dye in it so I will be able to find any leaks easier. My pressures are 22 low and 225 high. They should be 22 and 265 so I know I'm still a little low on freon. I had 10psi when I checked the system. It takes 42 Oz. Ive added 24oz. I'll add the additional freon with the dye.
If it does have a leak I'm almost certian it is the low or high pressure hose. They do look a little old. All conections would not set off the sniffer.
