Customer Question

Hi, well, son-in-law is always driving his pickup (Tacoma crew cab) in gear #2, not Drive. At both local and highway speeds. Can this cause tranny problems?
JA: How old is the transmission? Have you checked the brake switch?
Customer: Maybe 1 1/2 years old. Brake swwwwitch?
JA: What is the model/year of your Toyota?
Customer: 2016, leased vehicle. I suspect tranny problems or transfer ncase?
JA: Are you fixing your vehicle yourself? What have you tried so far?
Customer: N o, I have not used it ever. Just his wife and him. Seems that driving in "2" instead of "D" will cause problems?
JA: Anything else you want the mechanic to know before I connect you?
Customer: 2015 Tacoma. Highway speeds (70-80) in "2". Thank you.

Good morning,

Sorry about the "mechanic's assistant"- it's a robot and sometimes "her" responses don't make any sense.

So to clarify, he has it in "2" and is driving around everywhere in 2 rather than "D"?

Expert:  Jared D replied 1 month ago.

It's not likely to cause transmission problems, but it will definitely make the fuel economy suffer if the transmission isn't being allowed to shift into the correct gears. I've never actually seen someone do that before on a 2015 tacoms, so it's hard to say what the long-term affect might be. Doesn't the truck seem to run poorly like that?

Customer: replied 1 month ago.
Local mechanic says that the engine is damaged. And the truck is no inoperable.
Expert:  Jared D replied 1 month ago.

Oh ok. How long was it driven in 2?

It could have damaged the engine if he kept pushing it. It would be running at a really high RPM and either over-rev or over-heat or both. Did the mechanic say what is wrong?
