Ideal Shift points for 904

C2ndLTpigeon said
Hello,

I wanted to see if anyone might know what the target speed should be for 1-2 and 2-3 shifts in a 904 transmission? Im talking about a gradual up to speed transition and not WOT launches.
Mine will shift relatively close and pretty much be in 3rd gear at around 20 MPH.
Shift transition has been happening sooner since I swapped from 2.76 gears to 3.55's.
My 904 has less than 1000 miles on the rebuild and it also has a B&M shift kit installed.
Might need to adjust my kickdown.
Any help would be appreciated.

You need to adjust your kickdown in my opinion. I always set mine a little tight. The shifts are higher and firmer. In all the years of Mopars I have only had 1 Torqueflite fail and the link between the servo and the reverse ban fell out because the band needed adjustment. I lost reverse and found the link in the bottom of the pan. After I replaced the transmission of course. I was working at the speed shop and B&M Torqueflites were pretty cheap back then.
