FTI stall installed now slipping when ac is on? i am new to the forum i have a 69 chevelle with 2001 lm7 5.3l and 4l60e i was getting a shift solenoid b code i changed both shift solenoids with ac delco parts(new) put new filter (wix) all new fluid (valvoline dex/merc) and pulled trans to install a new FTI sb3000ls 3000 rpm stall while i was in there. stall works great all is good until i turn on my vintage air air conditioning and it seems to slip? it wont pull itself from a dead stop under normal excelleration like it does with ac off any thoughts? i am inclined to believe it electrical related as i after driving it a 3rd time got a new code for slenoid b electrical now.... thanks for your time guys!
