MSD Transmission control
Anyone familiar with the MSD box to control a 4l60E?
I have it hooked up and goes down the road but the shifting is very soft. Hoping someone could point me in the direction of setting for the Firmness, Converter and such. |

Re: MSD Transmission control
I thought what I read, that that was programmable

Re: MSD Transmission control
It is...but the instruction for install are great and easy to understand.
Advanced programing is very vague and looking for some help on how to stiffen shift points, and converter settings. I am a novice on automatic transmissions. I can take them out and put them in, I understand in theory how they work but much past that I am lost. I don't want to burn up what I have. It drives but is very soft on shifting |

Re: MSD Transmission control
What rear gear are you running? 2.73-3.07, will shift softer, than a 3.73 or 4.10. Cline, can tell more about the trans/ shift issues. He is the trans guru here Longhorn

Re: MSD Transmission control
Increasing the line pressure will firm up the shifts.

Re: MSD Transmission control
Does the MSD controller allow you to do that?

Re: MSD Transmission control
Yes just don't know where to set . Here is what it says but again I am a tranny novice.
SHIFT MULTIPLIER: Selection menu for scaling automatic upshift / downshift speeds (MPH). The multiplier range is 0.75 to 1.50 in 0.01 increments. Increasing the SHIFT MULTIPLIER above the default value (1.00) raises the upshift and downshift speed for a given TPS value. Decreasing the SHIFT MULTIPLIER below the default value (1.00) lowers the upshift and downshift speed for a given TPS value (Figure 9). TCC MULTIPLIER: Selection menu for scaling Torque Converter Clutch (TCC) lock and unlock speeds (MPH). The multiplier range is 0.75 to 1.50 in 0.01 increments. Increasing the TCC MULTIPLIER above the default value (1.00) raises the lock and unlock speed for a given TPS value. Decreasing the TCC MULTIPLIER below the default value (1.00) lowers the lock and unlock speed for a given TPS value (Figure 9). Figure 9 FIRMNESS MULTIPLIER: Selection menu for adjusting part throttle shift firmness. The multiplier range is 0.80 to 2.00 in 0.01 increments. Increasing the FIRMNESS MULTIPLIER above the default value (1.00) increases part throttle shift firmness. Decreasing the FIRMNESS MULTIPLIER below the default value (1.00) decreases part throttle shift firmness. WOT shifts occur at maximum firmness and are not affected by this multiplier (Figure 9). Warning: Decreasing the FIRMNESS MULTIPLIER value will result in lower line pressure at part throttle conditions – resulting in possible slippage and damage to internal transmission components. Used or worn transmissions will be more susceptible to damage sustained while |

Re: MSD Transmission control
You are right, it is adjustable!
Take one step at a time and see if you can feel the changes, but use more than .01 maybe .25 ...... just say'n!!
