A couple of Tranny questions

I have a couple of what I think are easy tranny questions. I guess they aren't that easy or I would already know the answer.

Did they ever make a wagoneer with a lock up torque converter?

If so what years did they do it?

If so can a tranny from a none lock up jeep work in a lock up one with the correct torque converter and keep the lock up?

And last will a th400 that was behind a 304 bolt up to a 360 that had a 727 behind it? I know it will work but is it bolt in or is there mod's required?

Thanks in advance

Yes, there was a lockup 727. Don't know what years, but it was mechanical, so it only requires the correct tranny and the lockup converter. You cannot put a lockup converter in a non-lockup tranny.

Yes you could use a TH400 from behind a 304 but you will need the flywheel for a 360/TH400 combo and there is a bushing that goes in the end of the crank to center the 400's converter.

Ok so is there any way to identify them, I would think that my 90 waggy should be a lockup, but who knows what has happen to it in the past 18 years.

This would also mean that the overhaul kits would be different as well (right?)

Thanks Ristow

Now I'm back to how do I tell the two apart. I trashed my front drum and need to do a rebuild but wouldn't mind putting in a lockup tranny. I know the trans has been out by PO but don't know any more then that.

non-lock will have an input shaft with splines going to the end. a lock'r input shaft will have a spindle-smaller diameter than the input shaft splines-on the end of the input shaft,that spindle engages the lock-up piston.

Ok I can't work on the wag since I have been stuck at the hospital all day. So I will bug you all for some more knowledge. Is the input shaft the only difference (besides TC) in a lockup tranny and a non lockup tranny.

If so can I put a lockup input shaft into a non lockup tranny?

Is there any disadvantage in putting a lockup tranny in my waggy(or advantage)?

Remember the transmission has to come out anyway if I want to go over 50 mph (no drive).

Thanks again

you'd need the valve body,pump,input shaft,and a case with the additional port for the conversion.

I found a lockup trans out of an '83. As far as I can tell they did not put lockup converters in wags with the towing option and most if not all of the later cars had that option.
Another way to tell a lockup from standard is the shape of the T/C. A lockup converter is flattened on the front surface against the flywheel; that is the surface that the friction disc inside presses up against to lock it, so it is squared off and flattened. The T/C on a non-lockup trans is rounded on the front.

I was hoping to find one to rebuild before mine went out but have had know luck and all the ones I can find now are still in the truck so I can't tell if they are lockers or not. I'm not really in the mood to pull these trannies just to find out it's not the one I want. Would I be able to look at the TC though the inspection cover if the owner will let me?
