does the smarty jr change anything with trans as far as shift points and line pressure,

 

No it does not.

 

Our trans isnt Electronically controlled as the Ford/Chevy...think only 4th gear....so not in the sense your talking about.

 

I have found that different TMs seem to effect the shift points. I think this is because the different TMs effect where the power comes on for a given throttle (or what ever the heck to call in on diesel). The trans uses the same throttle position for shift points. It isn't so much that the Smarty effects the shift point but it effects the power at a given throttle position. Higher TM settings seem to shift at a lower RPM.

Or it may all be in my mind!

 

Yes the higher TQ settings efffect shifting to a point, as with the higher settings the throttle position signal is manipulated so with higher tq numbers the ECM sees throttle movement sooner than on lower settings.

With the transmissions, they use a TV motor or cable depending upon year of truck. With lower pedal movement the TV doesnt move as much which means less line pressure which menas different shifting and different firmness.

Hope I explained this ok....

Basically higher TQ settings means lower line pressure due to lower TV movement and lower line pressure changes shift patterns and firmness.

Thats why a lot of guys add a sift enhanser to their trucks..it add more line pressure on higher settings.

 

where do you get a shift enhancer

 

Got mine from DTT Transmissions.....
