Remove CPS before you unbolt the transmission. Do Crusiers tip on the sensor before you put it back in. (it makes a noticeable difference)

Ill have to look into that. CPS is only thing I have left to unhook. Then I'm going to break the bolts loose so theyre ready to go tomorrow for the swap.

I recommend removing it - I managed to smash mine up pretty awful getting my BA10 out because I left it there. 

Will do thanks for the advise.

Also how much does the ba10 and ax15 weigh individually? I only ask because I will have to haul them in my hatchback unfortunately. Ive read about 100lbs a piece but idk how reliable that is.

4x4 AX15 is about 90lbs, and the BA10 feels slightly lighter than that.  2WD is probably a little heavier, so I bet your 100lb estimate is right on the money.

The 2 bolts on the top of the bell housing are a "PITA" and they have the star head to boot!

E20 is the type and size (or E12) I don’t remember

I heard a 12 point some size socket works in a pinch

I have not tried a 12 point. Previously when I removed those bolts I throw them away and get hex head bolts

It's E12, and I don't recommend a 12-point - that sounds like a good way to start rounding the head!

Inverse torx sockets are available from Home Depot, Lowes, and most auto parts stores.  Also Amazon, of course, if you can wait 2 days.

I seen that. I went and bought a set of torx (and inverse torx) sockets for it. I also sprayed some penetrating lubricant on the bolts again last night. I'm hoping that they arent too much of a pain. The guy i got the truck from replaced clutch roughly 3 years ago. I also went and bought a transmission jack just to be safe. Tomorrow I'm going to get this thing dropped and in the evening a friend of mine is gonna come help get the new one in.

I went to harbor freight. So hopefully they survive this job haha. If not my dad has a set of good ones i can pickup.

Thats a good idea. Might do that as well.

yeah I agree I just heard that somewhere probably won't try that

If you strip the head of those, you are going to be in a "fix for sure" trying to get it out. 

I tried the socket trick with no success. Went to Harbor Freight and bought the socket set and have used 6 or 7 times now.

inverse torx is so gross like why on earth. Does it stop thieves from stealing your trans :sad2:

I invite any and all thieves to come steal the transmission that's in it. Save me some work. 😂

It makes manufacturing easier.

Any advise for the CAT mount in the cross member? Looks like it could slide out. Also I leave the straps on the new slave cylinder when installing right?

how?

The Torx bit was developed by The Camcar division of Textron.  It’s design is similar to that of a gear tooth (technically it’s an “involute spline”) and it spreads the fastener driving force over a larger area.

 

The MAIN advantage is that the tools used to drive Torx fasteners last MUCH longer in a production line environment.   
 

So now you know....😉
