Manual Transmission needs Replaced

This is crazy. Did you get a loaner vehicle or a paid-for rental?

Have you tried to have the dealer or Toyota buy it back from you so you can move on? I would be calling them every day and being a thorn in their side.

 

I've never went through it before but isn't the lemon law only 30 days with out the vehicle? May want to try that I think each state is different.

 

What state are you in?

 

I'm in CT and it does look like if your truck is at the dealer for more then 30 days you can try the lemon law.

 

Junk ! This is why I would wait a full model year before purchasing any new model rollout, get some of the major bugs worked out first.
I would be major PISSED !!!!

 

Update, toyota says it is the transmission and ETA of July sometime for a new one because of backorders

 

Guess the one I’ve ordered for my truck as a conversion will hopefully be available at the same time….kinda nervous to use it if they are having troubles. I still am skeptical that anything is wrong inside the transmission though. I wish we could test the bad ones with a 3rd gen shifter.

 

I wonder where Toyota stores a transmission like that for warranty repairs.

 

You ordered the transmission from the 4th gen to swap into the 3rd gen?!

did something go wrong with your current transmission? Is it a direct swap? How much did the new transmission cost to order? I have so many questions haha

 

Yes. It’s the RC60F, there has been a thread on here for some folks who have wanted an RC60F for about 5 years now. It has different (read: better) ratios. That transmission was only used in the Hilux and some other overseas vehicles up until now with the 2024. That makes sourcing one domestically much easier. Before, ordering a Hilux trans was a real problem and even more expensive.

No, I don’t have any transmission problems currently. Just want it for the better gearing. Lower R, 1, 2, 3, taller 5, 6. Will pair well with my 5.29 axle gearing.

Yes, direct swap with the new 2024 model assuming we install our shifter and bellhousing on it. Previously, if you tried to use the one out of the Hilux, it required a full disassembly to change the input shaft because the input shaft for the diesel motor was too short to reach our clutch. The 2024 I4 and 2016-2023 V6 use similar depth clutches and so the input now works for the V6.

Cost me $3100 to order.

 

That’s pretty awesome, I must have missed where it’s a direct swap. Are you also swapping out the new metal clutch assembly from the 4th gen into yours? That was the one big change I was jealous of.

Are you doing all the work yourself? If so you should definitely make a thread about it

 

Yeah, Jeff Lange made it known in the 2024 technical details thread. I ordered one as soon as it showed up on Sparks Parts, 33030-04080.

I already swapped to the FJ metal pedal, I am not sure if the 2024 will be using the same part number pedal or not but it looks identical from what I can see below the dash in photos of the new truck. I am very happy with that swap, the pedal feels very secure and makes no noises. I forget the exact mileage I was at but I think I have around 15K on it now. Works great. I wrote a how-to write up on that one, check my started threads if you want to see it.



I will be doing all the work myself, yes. I will create a thread when the time comes with plenty of photos, comparisons with the old transmission, parts needed, etc. I just wish the dang thing would ship. I bought it in February. It’s still backordered, like this thread has touched on.

I’d really like to do a before and after video of the tach/speedo running through the gears. The before would of course have to be taken with a grain of salt because I have lower gearing than just about everyone. But it would show the difference between the two nicely. Problem is, I don’t have a good camera for that.

 

If it was a clutch issue, it would affect all gears.

It would be interesting if one of these dealers with the issue actually took something apart to find why it won't select those gears. All of the parts of the transmission are sold separately and there are no new parts in the 2024 Tacoma's transmission except the shift lever and bellhousing, so there's plenty of availability of service parts.

My money is on the issue being something to do with the shift lever extension housing, though it is a very simple mechanism that is basically a carryover from the Hilux as well, so not sure what could be going on there.

The 2024 Tacoma transmission is more or less identical to the 2016-2023 Tacoma transmission with gearing pulled from the Hiace/Hilux and an added input shaft speed sensor.

An issue of this type for such a carryover is unusual.

Mine is a 2024 sr5 and I just lost 2,4,6 gears. Waiting on a tow truck.

 

Another one. I really want to know the cause of this problem....wish a dealer would detail out a real diagnosis. Maybe this time.

 

How much mileage? Build date?

 

I'm also curious. It's interesting to me when tried and true components start giving issues with minor changes

Also are the 3rd gen guys supposed to carry the torch and start talking smack about 4th gens or are we all friends now? Asking for a friend

 

I am hopeful it's just the shifter extension somehow suffering a design flaw. Internally, the 2/4/6 gears don't seem to share much in common that would cause a failure there, and like has been detailed out, pretty much every single internal part is reused from some other platform. It is a strange problem for sure. Just need a real diagnosis instead of "needs a new transmission."

Considering I truly do not think my truck generation is better than the 4th, I'll be friends. The 3rd gens had manual trans problems back in 2016-2017 or so as well, with a sticky detent that made it difficult to remove from 5th and 6th IIRC. They fixed that one after around a year with a redesigned detent. Hopefully they make an official fix for the new trans soon and it's made known what the actual issue was.

 

629. 12/23

 

When I traded my '23 3G in last month, it had FOUR open recalls. So, we are hardly in a position to trash the 4G. I will say that I find the 4G to be not only incremental, but in most ways, incremental in the wrong direction. Bigger, heavier, more complicated, without any benefit in interior space and, in most lower trims, only 100lbs more capacity.

These transmission problems are a surprise, given the extent to which the 3G MT is similar to the 4G. Maybe a supplier change on the synchro components?
