Ok guys, this is going to sound a bit weird but I’m wondering if anyone else has this problem or knows if it’s normal. I have an 18 SV crew cab 2 wheel drive. Love the truck but this one oddity has got me stumped. Fairly often, when driving in first thru third gear, the engine noise will about double. It sounds like the motor is reviving really high but the tach isn’t moving. It sound kinda like transmission slippage but the RPM aren’t increasing so it’s mot slipping. Acceleration seems slower when it does this as will. Doesn’t do it when I’m about 35-40 mph either. I’ve tried shifting it manually but that doesn’t help. Just hate the added noise and the lesser acceleration. Any ideas or info would be appreciated.
