5vz Trans swap

I think we can all agree the A340 Trans is pretty sluggish. I haven’t seen any forums about this but can you swap a better auto trans that bolts up (or has adaptor option). Give me ideas because I want auto because it’s built for off-road but the A340 just isn’t cutting it.

 

It's not the auto that's sluggish, it's the engine. Add a turbo (properly) and that thing will rippp. Definitely do a shift kit before any boost.

I've had a few different boost variations on the A340f and loved them all. Only thing is I didn't do the shift kit and started slipping clutches after a couple years. Also slipped the clutch with turbo and 5 speed so those aren't invincible either.

 

I have to disagree. The Torque converter robs so much and the 4 speed aspect is dog ass

 

Moar boost.

 

It robs boost too lol

 

Go manual.

 

Just boost it as is (SC or turbo) and tune everything properly (trans included).

Trust me, 6 psi with long travel and you will be having alot of fun. 10psi woo weee. Definitely run bypass and bump stops.

 

I'd agree. If you're willing to do a custom trans swap, give added power a shot first, and if you still don't like it, go manual. If you don't like that, time to get a different truck

That said, I'm still following for options

 

Want to go faster offroad? Suspension.

 

it’s supercharged with 7th injector kit and jba headers…

 

already done

 

what’s the shift kit? I’ve never heard of it

 

Look up TransGo reprogramming kit. Modifies the pressures in your trans and takes the slop out of shifts.
