Swapping Input Shafts for FJ Case for Manual Transmission

Ok so with this in the writing it said you need to swap the ring gear, because I’m a bit dense it means not using the original 6sp ring gear it means using the auto one correct?, and thanks for the write up on the add swap it will be very helpful.

 

the input shaft will need to be swapped from the auto case. They are a smaller 23 spline shaft and the 6 speed is a larger 22 spline input. No ring gear has to be swapped.

 

Ok so I don’t have to use the automatic ring gear on the backside of the planetary gear and input shaft? I can use my 6speed ring and it work fine even tho they are slightly different?

 

my apologies, yes what Randy is calling the ring gear you will need to swap between cases

 

Awesome thank you will post pics when everything is done

 

What wyatt* is calling that. I just copy pasta’d his whole thread.

 

forgot that you snagged it from his site lol, sorry. Yes I heard ring gear in my mind and was thinking R&P from the differential.

 

When he said ring gear I also thought diff during my initial read.

 

Ok which wires and and which plugs do I need to mess with to make my lights quit flashing fast? I saw the pictures but I can’t distinguish which plugs and which wires

 

check here there is wiring diagrams posted. To keep the lights from flashing in the mean time just remove the 4wd fuse.

Ok so doing my test drive the case is leaking fluid and it seems like it’s coming from the shifter how do I need to deal with this?

 

what shifter do you have? If OEM, make sure the oil slinger is installed.

 

The oil slinger is the piece that pulls fluid from the bottom of the case right? If so I have it installed

 

no that’s the gerotor, I hope you have that in

 

Then I don’t have a clue what the oil slinger is.

 

Did you use gasket maker when putting the shifter back on?

 

No I did not. I didn’t realize I needed too I never had to do it on my older Toyotas with Manual tcase

 

That may be your issue, a simple fix. There's a paper gasket there from Toyota so I used some RTV when installing mine, no leaks.

 

Ok so rtv got it

 

"No ring gear has to be swapped." I was going to say... WTF, because i sure changed out mine! But then i read further and see that you corrected your comment.. Pheww... (that was simi-fun part of the swap)

Somewhere on TW I recall reading the quote about the Threads aren't fun w/o pics... so enjoy some randoms from my (best yet) swap...
