gear change speed

Hi everyone, it's my first time on here , although i have tried before,my first problem was the aircon not working, that was because the clutch assembly was missing?, my new question is what speed or revs should my auto change gear, i think it might be stuck in sports mode,also on the over run i get a chirpping noise is this normal, thanks for any help

Exact speeds depend on how hard you accelerate! However, under gentle acceleration, 1st to 2nd on mine is at about 15mph, 2nd to 3rd at about 28, 3rd to 4th at 35. Torque converter lockup will be at 53 which feels like going into 5th! Unless you put the transmission in 3rd, and then it will lock at about 48.

Don't really know about the chirping on overrun - I haven't noticed that on mine.

Cheers!
