What would improve offroad performance the most

I’m not suggesting he own 2 trucks.
I was suggesting saving money to buy a different truck.
Then apply the money he has saved to the difference he gets from his current truck.
My suggestion would be different if he had 2 trucks ….now.

We can disagree. I am not changing my opinion based on the information I have now.
If he were my son, I’d tell him the same thing.
But I wouldn’t stop him from doing the swap if he wanted.
Like I said in a previous post. I did a similar thing when I was his age.
I really, really, hope it works out perfect. I hope he gets all the parts and it all goes together quick for him in the course of a single weekend.

Again, I’m not questioning his ability.
My suggestion is but an opinion.
He can do as he pleases.
If he lived close to me, I’d even help him. Even though I thought it was a bad idea.

There are two schools of though about when to used 4wd off road. The first school runs the whole trail in 4wd. The second school waits until they get stuck in 2wd then put it into 4wd just long enough to get unstuck. The though process with the first school is don't get stuck at every obstacle and stop the instant you can't go further. The second school thinks it's safer to keep 4wd as a backup only. I was born and raised in the second, keep 4wd for emergencies only, school. But as my off road experience grew I switched over to the first school, 4wd all the time. In the second school I was constantly getting held up on obstacles. Sometimes I'd get stuck in 2wd to the point where even 4wd was iffy on getting me unstuck. So, I joined the first school and driver right over obstacles that would have stopped me in my tracks in 2wd. Now of course I have to be careful to not go beyond the capabilities of 4wd, but after getting stuck in 2wd more times than I can count I got a feel for it.

FWD is the secret sauce of 4wd. You've got the heavy engine bearing down on tires that pull in the direction you want to go.

I had a Jeep rock crawler and fell to the wide tires are better trap. If I were to build another I'd find the skinniest tires I could.

 

@Michael05 - This probably goes without saying, but if/when you decide to undertake the swap I believe one of the biggest hurdles to be overcome is finding transportation while the swap is happening. Once that is in place, all the pressure's off. I'd hate to have to have the job finished in a weekend to get back to school/work on Monday.

 

Okay so I have done some reading and have several questions.
The above quoted material I do not completely understand. I plan on keeping my current transmission and and swapping the output shaft and bellhousing. Is the above quoted material irrelevant to me based off of my plans?

Another question. I keep reading things that mention a hose clamp on a vaccum tube. That is irrelevant to me because I plan on doing manual hubs correct? And if you have the spare time could you explain why they do it. I can't seem to find a thread that explains the why.

 

To swap the output shaft, you will need to salvage an A340F anyway, so why not swap the whole tranny? That's what I'm about to do

 

Because I was hoping I could find that sole part. I already found the Bell housing, I just need to find the output shaft part number. And again, I will not swap a used 4x4 transmission with unknown history when I can reuse my current and healthy transmission.

 

I would strongly suggest reconsidering. Nobody is going to have just that part and the only savings to be had are if the rest of the tranny is damaged that it comes from

 

Are you going to rebuild the transmission you purchase or just throw it in there how it is?

 

I'm going to hope the clutch plates are good, put the transgo kit in, and keep my old solenoids nearby in case the "new" ones are bad

 

Yeah see I don't want to have to hope it works. I want to know for a fact its gonna work.

 

I mean you're a new account so I don't expect you to know this but real tranny issues are RARELY a problem with these trucks, especially if the donor vehicle has no power adder

 

Yeah well what if your clutch plates are bad. How are you gonna deal with the transmission slipping all the time? Would you replace the clutch plates? Because at that point you would have spent just as much time with your transmission under the operating room lights as I would have if I swap the output shaft.
I will reconsider like you suggested, but I have to plan like the glass is half empty because this truck is my DD.

 

I would just tear it apart and take out the output shaft.... I have everything I need by buying the full A340F... or I'd take the opportunity to upgrade the entire thing

But I do agree with the others not to do something like this if this is your only vehicle. I literally bought a $500 car when I decided to turbo my truck and made that my daily

 

What do you mean by upgrade? Like send it to people to bullet proof?

 

They make higher friction clutch plates for higher power applications. 2JZ engines are related as they use similar transmissions

 

While I do agree that better internal components are good.
I think he will be fine with a stock A340F.
Maybe run a trans cooler if you want to be safe.

I don't think he needs to do anything other than swap an A340E for an A340F hah, that was just me who would want to upgrade if something was in need of replacement

 

I agree.
I’d swap the whole transmission.
Swap an A for an F

 

There’s no negative to swap the output shaft just it takes more time. Plus, I’ve always wanted to get to know the in’s and out’s if a tranny. We’ll see. I haven’t decided yet. Once I start sourcing parts I’ll decide which route I’ll take. It’s completely circumstantial.
