Hi, I've often heard from performance tuning companies and enthusiasts that tuning an automatic transmission to shift faster and increase shift responsiveness to inputs from paddle shifters, can reduce heat and wear, thus increasing the life of a transmission. For example, the 8- and 10-speed transmissions on modern American muscle and sports cars. TCM tuning seems to be rather common amongst enthusiasts of those groups.
I would like to remove the delay between shift request and the actual shift of transmission. However, I cannot find any source to validate or debunk statements that remove shift lag and increasing shift speed is beneficial for the transmission.
What are your thoughts?
Well those modern transmission especially the 10 speeds are so freaking complex I wouldn't touch it with a 10-ft pole. You start modifying things there's no saying what the end results would be
You might try to get hold of TCI or Monster Transmissions. These guys rebuild super duty and racing transmissions and have all the info you might need. Good luck.
Thank you.
