Auto vs Manual which one is stronger?

They don't have a transmission in the typical sense, they have a reverse box but not multiple forward gearsets. Clutch slippage is pre-set and the driver has no control of it during the run, he doesn't even use the clutch pedal once staged. The only way to have an unbreakable transmission behind 7000 HP is to have no transmission at all and to have a clutch that is idiot proof is to not let the idiot control it.

 

You'll likely kill the clutch in short order so while the transmission may still work, you still can't go. I've watched 3 different trucks have their clutches smoked on a boat ramp with boats well under 20k lbs., yes the transmissions were still working when the tow trucks arrived. My 1980 Ford with it's original auto trans pulled two of them off the ramp in reverse while pushing my boat up the ramp, over 30,000 lb. pulls. That same truck was used for towing for 20+ years with no transmission work and no modifications, often towing while hauling a big camper and in up to 120 degree days. When I sold it a few years ago the trans was still working perfectly. My brother towed his 15,000 lb boat to a mountain lake with a stock auto trans truck, no issues. I've towed my boats with my motorhome and three different Explorers, all autos with no modifications, none have failed. Before buying that '80 truck we researched many options and in every case the manual trans version of the same trucks had lower towing capacities.

Nothing I've read or written here proves or even provides useful evidence to which trans type is stronger.

 

My manual creeps in 4-lo easily. 4-hi I have to slip it a bit and have smelled the clutch a few times. YMMV.

Wheeling can be done either way.

That being said I would've probably gone with a full size if I wasn't able to get manual in the taco.

 

Ditto. Manual or Bust.

 

I don't think anything could hold candle to the old Powerglide 2 speeds that were and still are very popular in drag racing. You couldn't kill those things. There are some very good auto transmissions out there now that are tough to beat. I'm afraid the M/T's days are numbered unfortunately. Automatics are starting to match or beat them in MPG, are lighter, more efficient and much easier to meet emissions standards with. I'm honestly surprised Toyota carried any M/T's over on the 3rd gen Tacoma at all.
I'd say both Tacoma transmissions are pretty damn strong and will hold up however well you take care of them. I prefer manuals for towing and sports cars but that's about it. My current Taco's an auto and I'd never go back to a manual for a DD ever again. After a long, strenuous day at work, the last thing I want to be doing is rowing gears in stop and go traffic that's barely creeping along.
