2024 Tacoma Transmission Overheating on Long Climbs Off-Road

[px3_taco]

I saw some snippet that it doesn't happen on trucks with the tow package. Anyone with the overheating have the tow package?

Is this the sensation I get of a slipping trans? I swear the first time I drove it, I thought it had trans issues.

It's just got a high stall converter (I think), not slipping. That's why it makes CVT noises until it shifts when you firewall it. I think personally they went high stall to protect the drivetrain both on and off-road, and maybe even to protect the engine from ending up in high-load-low-rpm situations.

The M/T is tuned to have peak torque at 3000RPM vs ATs 1800, I believe this was to prevent people from flooring their truck in 6th gear on the freeway and doing a GR Corolla engine popper Turbo engines hate nothing more than high-load-low-rpm, that's how you get LSPI ie, super knock.

I really think it has something to do with the comically high stall converter these things have. It makes it fast for sure when you get on it, but Toyota has gotta make em lock up in 4Hi way sooner than they do.

On the street when you punch it, it spins to like 3000RPM for 2-3 seconds before it locks LOL it's cool but if the truck was slower and shifted sooner I wouldn't mind..

Edit: Does MTS ever request that the driver switches to 4Lo? Depending on incline? Descent control I can see it wanting 4Lo. Not sure about climbs though.

This, its comical, people hate CVTs and Toyota managed to make an 8 speed CVT…

When you drive normally though, 1/4 throttle to 1/2 throttle it shifts fine, like a conventional auto.

I was riding with a friend and he noticed the high stall too so I don't think its all in our heads

There's not much besides the torque converter that makes heat in an auto so

Wonder if this can be tuned out without issues... Its extremely aggravating for me since I have a TRD PRO and the exhaust is loud... so the exhaust just remains at the same pitch and volume like and old clunker when accelerating.

Toyota are you listening?

I will say that I don’t mind the transmission behavior most of the time but I do agree with the high stall speed. I put the TRD exhaust on my truck and it’s become much more noticeable when the windows are down. Especially if you’re driving through a tight street and the exhaust is bouncing off of homes/cars. The exhaust sounds good for an I4 otherwise but nothing sounds good when the rpms stick and it drones. For this reason I may end up putting back on the stock pipe some day. We’ll see

that is exactly right… transmission sticking + exhaust kills the fun.
