Which 4wd V6 trans is stronger?

I'm not sure exactly what you mean by stronger.. whether you mean which will take more abuse or which will handle more engine torque.

The forced induction guys are burning through clutches and I haven't heard of any complaints from the auto transmission crowd. I do hope the manual RC62F will easily handle an extra 100hp/tq with just a clutch upgrade.

Perhaps I just have confirmation bias from watching the NA/T (turbo'd) SC300 2JZ manual guys burn through w58 transmissions when the auto transmission would hold the big numbers.

// R154 ftw (Edit: Actually it's the R160 Getrag which I believe was the super strong manual transmission used in Toyotas.)

 

In addition to a Tacoma, I have a M/T 1991 Cummins turbo diesel, owned since new, and a '93 MR2 M/T turbo, owned since 2000. So I am a forced induction guy and I don't burn up clutches because I know how to properly drive a M/T. Some folks on TW do not.

 

It's that instance of having something then it's gone now you want it back. I've had 5 trucks and only one had the shortbed, never again

With the shortbed I always wished I had more room, I never thought I had too much room when I had the longer bed even with three single cab trucks.

The shortbed does not work for me, especially with a bed mounted toolbox.




Bikes are in and the tailgate is up, no obstructing the backup camera.

I can also haul all five with three in the bed and two on the tailgate hitch holder because the tailgate stays up.

 

Seems backwards to me, what’s your thinking?

 

Idk what year automatics your meaning, but my 2020 bone stock sr5 auto shifts spot on with the road, and load conditions just as good as any automatic i've driven in the past of any manufactures vehicles. Maybe they did in years before that, but thats not the case anymore.

 

Opinions on this subject seem to shift automatically depending on who you ask; there is no standard.

 

How hard are you on a clutch. MOST people will have to have a clutch replaced long before an AT will need repair. I vote that the AT is stronger as in will last longer without repair. I’m sure the MT folks will flame me.

 

The manual has a lower geared rear end so you have an easier time getting it moving. Also, stock auto is just awful and lethargic. Manual transmission is forgiving and responsive. My wife learned how to drive it, however she refuses to drive anymore because apparently I get loud when I educate ‍♂️

 

Did you even read the thread title? I don't think anyone is complaining about getting their truck initially moving except for perhaps a manual in reverse.

Awful and lethargic? Get a grip dude.

The thread is about "which transmission is stronger" if you need a clue.

 

I mean my auto was pretty lethargic until i got the ECU tuned…

 

SR-5 All the way

 

oh I’ll get a grip alright. A grip on that SWEEEET shifter and row my happy self down the road without worrying about hammering a pedal that doesn’t like to accelerate. I gave my opinion about what I think is “stronger”.

 

From everything I can read, the RC62F seems to be stronger than the AC60E/F in terms of holding torque. I base this mostly on the AC60 being used in 4 cylinders and from what little I can gather on the Aisin website. I believe the RC62F can hold somewhere in the 400 ft-lb range, but the AC60E/F auto is hard to find anything concrete on.

As far as stronger in the long term, I believe the manual transmission takes the win for one main reason: The automatic is a closed system which is more tedious to maintain or check the level or fluid condition at the weep valve (I suppose you can slowly open the drain until you see a drop to check the condition). The manual is a simple drain and fill which promotes easy DIY maintenance. This is not to say the auto can't last hundreds of thousands of miles without issues, and I think I'm splitting hairs in stock form for the most part.

So in the words of Paul Harrell, "For our purposes here today, if one is stronger than the other, is it stronger enough to matter? You be the judge."

 

How about when I had shoulder surgery and couldn't use my right arm for two months, luckily I've got a automatic, or when my mom broke her right foot and couldn't use the clutch in their manual car.

 

Have you tried towing 4-4.5k with a manual? It’s fine once you get going, but taking off even on a slightest hill, kills the clutch. Reverse is super tall, requires 2WD low mod to maneuver the trailer without destroying your clutch.

If where you live is flat, than manual will be ok, but your clutch won’t last. I live in a very hilly region and I will not tow more than 4.5k, no way. 2WD low mod was a huge lifesaver when I was parking the trailer.

Also, IMHO torque converter is a stronger unit than clutch, for towing.

 

Fair enough.I can see the short bed being almost useless with a tool box. I honestly have never once wished I had a 6’ box, that’s why I was curious.

Some more pics of my crazy loads haha.

 

They stopped putting manual transmissions in school buses 40 years ago. You haven't been able to buy a 3/4 ton or 1 ton truck with a manual for years. Some of those are rated to tow almost 30,000 lbs. Virtually all big rigs are now coming with automatic transmissions.

If you need work done, buy an automatic. If you want a sports car with a bed, buy the manual. And I'm not saying there is anything wrong with that. I enjoy stirring the stick when driving occasionally. But any more a manual is just for fun. From a practical perspective an automatic does everything better. Will last just as long too.

The manual transmission, and the engine in Tacoma's are designed for cars, not trucks. They aren't geared low enough in 1st or reverse. Couple that with an engine that needs 4600 rpm to develop torque makes a manual a huge disadvantage getting a load moving. Back in the day my 1985 F150 the engine got its torque at 1700 rpm. And 1st and reverse were geared much lower. It was slow as hell, but you could put it in 1st gear, let out on the clutch at idle speed and move 10,000 lbs.

How is that. I've never seen an automatic where the driver didn't have control of what gear it needed to be in. If you need more rpm's to get the power you need then manually downshift the automatic to a lower gear. For normal driving let the transmission do it's job.

 

The auto is much more complicated. They have more parts than the motor itself. Manual is simple: steel gears bathed in oil.

 

I need the extra room for my 6ft ladder and staging. I do not want to be driving down the road like the Clampets. Also, can fit a 28ft ladder without a rack. Saves me from driving my flatbed from job to job. Not even going to mention the option of sleeping in the back.

 

As a class A CDL driver I can tell you for sure this statement is false.
Maybe the mfg’s are pushing Allison’s for day cabs but OTR is and will stay dominated by the 8 and 10spd Eatons for years to come.

Doesn’t matter how much power you put in front of the Allison or how strong of a transmission it is (it is a great automatic tranny, not trying to downplay it) they’re just not geared right for over the road hauling, especially in mountain regions.
