32RH lock up or non-lock up Torque Convertor

I need some help identifying whether or not I have a lock up or non lock up torque convertor, The Jeep is a 93 YJ with a 4.0 32RH 3 speed auto.

The guy at Transtar was unable to tell me but mentioned that the input shaft of the Trans hsould be osme type of indicator... Any help would be greatly appreciated!

The converter is a three element unit, impeller, stator, turbine.
It also has a converter clutch. It is controlled by an electrical solenoid and a mechanical clutch module on the valve body. The solenoid is operated by the PCM

Hey Laybackman,

Thanks for the information, I saw your post earlier today when searching for info. With this information, does this mean that all the torque convertors for this trans are the same? There is not specific lockup and non lockup type?

Please confirm.

From what I have for information all 30RH and 32RH tranny use the same type of TC.

The number of splines should tell you. 26 splines is for the Lock Up, and 27 splines was non-lockup.

So now I have mixed information, can someone confirm either way? Are all torque converters the same for the 32RH, or do they really have two different spline counts?

My info came from a FSM BUT that does not mean they are correct. They often made mistakes in printing those books up.

Check the spline count on your and replace it with the same type!

OEM part number 5211 7877 according to the OEM parts manaul

The shop that rebuilt my '94 automatic ordered the Tc from his supplier, and they gave us the Lock-Up unit, and it would not fit/install. Only after counting splines and doing some on-line research did I discover that it was for a Lock-Up tranny, and as I suspected mine wasn't I found the Non-Lockup was a different spline count, they admitted their mistake and shipped me the correct unit.

26 splines (Lock-Up)

27 splines (Non-Lockup)

Thanks for all the help guys! With the info that I got in the last post, I was able to confirm that I have a no lockup converter. And of course like most others got the wrong one first!

So just to confirm, 26 spline count is the lock up style

And 27 spline count is the no lock up
