[DML] Re: Automatic transmission shift point



Are you driving it hard or "normal"? If you hold the gas pedal to the 
floor and then back off when it shifts 1-2, it will do exactly what 
you describe. If it is doing this on normal, gentle acceleration you 
may have an issue. 

"This sucker's electrical". There is a very slight adjustment on the 
throttle position cable (the upper cable on the throttle spool, the 
other end is at the transmission). If this cable is adjusted 
improperly the trans will shift "late", i.e. as if you had your foot 
on the floor. If the cable is disconnected or broken, it will shift 
early no matter how aggressively you drive. 

On the assumption that you are not drastically letting go of the gas 
pedal at the time it shifts 1-2, you likey have an issue with the 
computer governor (the white box on the side of the trans). This 
controls the shift points by measuring a voltage generated in 
proportion to the car's speed. If something in one of the two 
comparator circuits has failed (including the notorious input 
capacitors) the shift points will get screwed up. 

You probably need a new (or rebuilt) computer governor. There is no 
adjustment other than changing the value of some components inside. 

More to come later......
