Auto transmission Shift Points Changed

[CDretzka]

For no good reason the shift points in my 1998. 5 changed from 1900 rpm from 1st - 2nd and 2nd - 3rd to 2500 or 2600 rpm. I have BD low stall TC, BD valve body and BD pressure lock. 50000 problem free miles then like some one flipped a switch it happened. shifts are still crisp and there appears to be no slippage. 3rd to 4th and lock up all occur normally.



This is very annoying as 25 mph = 2300 rpm with 4:10 rear with the 4" straight exhaust neighbors are starting to gripe



Help... . is there a valve body problem here or sensor gone bad?

I'm no trans expert but have you checked the kickdown cable? If the cable came loose then I think this is one possibility for the problem you are having. I adjusted my shift points this way. I'm sure there could be plenty of other reasons for your problem also. Good luck.

does your throttle pedal feel light all of a sudden ?

i'd look at your pressure lock , if its sticking it will be pushing on the TV lever and that could affect your shift points .
