If you want to save fuel and keep the acceleration,just buy 13 or 18 speed with taller final drive
this mod is pointless

I’ve gotten MUCH better fuel economy in game with the default transmissions, when going approx 65-75MPH (104-121kph) when on the highways, usually getting around 6-8MPG (39.2L/100km to 29.4L/100km)

i use this tranny with adaptive tranny mode and whenever a light turns green and i open full throttle the tranny sticks in D2 and climbs up to 2300 then just continues to sit in D2 instead of shifting so i have to get out the throttle by 50% in order for it to shift and i know its not the adaptive tranny mode because all the other trannies ive use even it Adaptive Automatic Mode on the truck will shift at 2k all the time when im full throttle but can you take a look at the 8 speed because its not shifting from D2 when throttle is wide open.
