2015 Toyota Tacoma Transmission and drivetrain Problems

“I purchased the vehicle new & had the dealer install the optional Toyota trd supercharger at approximately 5k miles. At approximately 10k+ miles, I started to notice while at cruising speed (30-50mph) if I needed rapid acceleration to pass or enter the highway, the tachometer would show the engine revving but the vehicle will not accelerate. The vehicle is used for commuting 100 mi daily (highway)the Toyota dealer confirmed the problem / removed the transmission to access the clutch & found no abnormal wear or defect. …”

Truck requires that you put it into park and back into drive before you can proceed. Last time this occured I nearly hit a child in the street as it rolled backwards and would not engage even though it was still in drive. It's been into the shop, nothing they could do and I have emailed Toyota. …”
