6spd manual transmission differences

Does anyone know the difference between the RA60 and the RA60F transmissions? I believe the 60 is the 2wd transmission and the 60F is for the 4wd, correct?

I'm toying with the idea of changing out 6th gear for one that will result in lower RPM's on the highway. I've found a RA60 for cheap, but I don't want to buy a very large paperweight if the two transmissions are not interchangeable.

Thanks for the input

 

bump. bump. im in the same boat with you man, i love every gear as it is but 6th is rediculous. like they planned on me towing max cap and not knowing how to downshift or something.

planned obsolescence: make the manual inefficient so the autos can take over the world

 

The RA60F doesn't have the output nose for 2wd afaik.

If you want to start looking at swapping 6th gear, the one to measure would be the 6th from the FJ. It's taller than the tacoma's by a little bit but not much. It would be easier if the FJ tranny would just bolt up but no guarantees either way.

 

hmmm sounds like a job for marlin crawler. make us a gear!

 

External overdrive would be nice...

 

Subd. 6th gear on the highway with cruise control is high in the rpms

 

RA60 (2WD 6 speed)
4.171
2.190
1.488
1.193
1.000
0.849

RA60F (Tacoma 4wd 6 speed)
4.171
2.190
1.488
1.193
1.000
0.849

RA61F (FJ 4wd 6 speed)
4.171
2.190
1.488
1.193
1.000
0.799

I read some mention of the output shaft being a different size on the FJ, but haven't confirmed that. So what would be the RPM difference at 70mph with the 0.849 gear vs. the 0.799 gear?

 

That's easy math. 70 mph is about 2550 rpm on stock 245 tires.

difference ratio = 0.799/0.849 = .9411

0.9411*2550 = 2400 rpm

Not that much of a difference.

If it was something down around 0.70:1 like the auto, then it would be more worth it. I doubt you'd recoup the cost unless you found a tranny for super cheap.

edit: another way to think about it, that gear would make the truck cruise as if it had a 3.51 rear end instead of the 3.73.

I wonder if one could swap in both the tranny AND transfer case, and convert the truck to AWD... of course, there go the mpgs anyways. T'would be killer in the snow though.

 

That's not much

 

I agree, manual transmissions in the US have been lacking miserably in quality and performance in recent years. One day I fear they will no longer be available in the US at all. That is why I am going to try and hang on to all mine, I won't let my kids grow up on automatics if I have kids someday. My dad made sure I perfected the stick shift before I even touched an auto, I was so good at it that by the time I took driver's ed, my left leg did not know what to do, that D.E. car was the first car I drove with an automatic transmission. Only car companies that make really good manuals are the European car companies in most cases, I love the 5 speed in dad's company Jetta, so smooth and slick. But the Europeans are still crazy about manuals and 90% of cars sold in Europe have a manual transmission, so the engineers put effort into making them the best they can be and have pioneered that technology. On the other hand, it's almost the complete opposite in the US because this country has become too fat and lazy to drive manuals. I know a few kids in college, mostly girls that have no idea, or have never even seen a manual tranny before! I don't have anything against autos, but come on, it's time to manual up America!

 

Why? All i learned from learning how to drive in a stick shift car was that driving a stick shift sucks. Auto ftw.

 

I take it you drive a manual to account for you lacking in penis size?

 

All I learned from driving a manual is better control over my engine speed and thus torque curve at any time. I also learned that an automatic in the same car can suck away as much as 25% of your avaible horsepower due to gearing and ineffiency of the transaxel. The most important thing I learned about a manual transmission; they are far better for control of your vehicle when you most need it.

In Toyota Nomenclature the F on the end of a transmission number always means that the transmission is deisgned for use with a transfer case.

 

Back on topic. The real question is, is there any room for a larger gear in the housing. Has anyone found a spec that shows clearances?

 

That is my biggest annoyance with this truck. It revs much too high on the highway in 6th @ 100kph. I do find with the bigger tires that I can reduce my speed on the speedo to 93kph and still be doing 100, and hence the engine is not reving as much but its only reduced by 200rpm perhaps.

Even if there was a bigger gear out there, doing the switcheroo would not be easy nor cheap I would think.

 

Nice thought, but I'm pretty sure that won't work for a 4wd truck. Please correct me if I'm wrong.

 

Drove a manual car for 6 years. Came to a point where having manual in a work truck was annoying. After surgery on my left knee shifting put unnecessary fatigue on my knee and it would hurt towards the end of the day. Big chunk of my meniscus was cut off. Auto FTW in a WORK truck! Yes if I would ever get a fun weekend car it would definitely be manual.

 

How about you grow the hell up? Why does everything around here have to be centered around penis size? It doesn't fucking matter what the size of someone's junk is for Christ's sake...

 

Well I drive a stick and if anyone wants to talk about my penis size they are more than welcome to.

 

And so it goes. The auto as we know it is going to be doomed to the dustbin of history as well - the future is in the CVT. And once the ICE becomes obsolete, electric motors....

The automatics are very nearly there - finally reliably delivering equivalent or better performance than a human in almost every use case. The auto in the Tacoma is a fine piece of work and a good transmission. The only reason to choose a manual is because you prefer it.

Don't get me wrong - I prefer my manual as well and driving loses a lot of it's charm when that sense of connection is lost. However, people used to do all sorts of things manually and now we automate it because people suck at it in comparison to machines.
