Transmission wear from incorrect driving

I know the post title is odd, but here's the story:

My wife and I have a storage space in Indiana that we never fully cleared out when we moved to VA. She wanted things out of it, so I let her drive the truck up and back.
She admits to me today that on the way there and back, she wasn't paying attention to the shifter, and drove for portions of the trip with the transmission in 4th, not D. This means a couple hours at least of being run in 4th at 70 to 80mph.

engine/trans is V6 auto. Vehicle had 1500miles on it at the start of the trip.

What sort of damage am I looking at having to deal with?

*edit* setting for tans was 2hi

 

Nothing to worry about, I tow all the time in 4th gear at those speeds.

 

Yep

 

You need her to reimburse you the difference in gas cost of the trip!

 

Ouch... only 1,500 miles, basically a brand new truck. Doubt you did any damage to the transmission, I'd be more worried about the engine since it's still in the break-in period and was kept revved nice and high for hours. I don't think you did any damage, I'd just be a little irritated if I were you but at least she told you...

 

Like what has already been said, no harm, just wasted gas.

 

You'll be fine. Shit happens. I've done it once or twice. The auto has fairly tall gears, so unless she was really speeding, you weren't pushing the RPMs that high.

 

Shouldn't worry about any damage or "break-in". You're truck's just fine.

 

I wouldn't lose even one minutes sleep over that incident.

 

You spoil your Tacoma. I bet you washed it for forgiveness.

The truck enjoyed every minute of it I'd bet.

 

lol when i first bought my truck, i was driving for 30 mins with it in 4 not realizing I was not in D.

Had an 02 Taco before. Was noticing how it was a little louder on the highway. Then looked at the dash and noticed the "D" icon..... Look down on the stick and ooopsy.

 

it ok to downshift the auto right???

 

Yes , no problem at all .

 

it's a truck tranny with the tow package i assume, this means you'd have trouble damaging it.... I used to drive in 4 all the time cuz the dealer told me it was like sport.... dumb dealer.....

anyway, my bmw went through 3 trannies from doing somthing like this, cuz id drive it a gear down to keep it revved higher during spirated drives, but on my year bmw, BMW had outsourced the trannies to GM so i got crappy tranny...... this was the reason i went to a tacoma, for the tranny that could rev high without blowing a hold in the side (no joke)

 

Wow...and she didn't hear the rpm's screaming at her?

 

Thanks for the info. I didn't want to assume all would be well. Figured it would be better to ask around.
