Q: I'm coasting 10 mph, my truck is in 3rd gear - should it miss 2nd completely & go to 1 when it finally stops?

asked by on

It started out with a loud vibrating sound when driving 30mph and faster. Kind of like I'm on rumble strips and then when letting off the gas pedal, it sounds like a Blackhawk helicopter is landing on top of my truck. Next day, I notice my rpm's are irregular. Not jerking or clunky but I barley touch the gas and they fluctuate or bounce around between 2,000-3,000 with no response from the motor. Humming / vibration/ helicopter sounds all still happening. I decide to head home and notice that when I'm traveling anywhere between 3 - 15 mph and apply the brakes, the transmission stays in 3rd until I'm almost completely stopped, then goes straight in to 1st. Totally missing 2nd gear every time

Hi there. It seems that the Electronic Pressure Regulator Solenoid (EPRS) number 3 has failed or is dumping fluid back into the transmission pan. The EPRS pressure solenoids are designed to direct fluid to specific clutch packs. The EPRS solenoid number 3 operates 2nd gear and 6th gear. If the solenoid is weak, then the fluid will not apply the gear properly and cause the clutches to slip. The noise you are hearing is the clutches slipping on a large scale. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission noise.
