Hello everyone!
I have a strange problem on a Clark GCX15E that started rather abruptly according to the operators.
They called me complaining of a noise from under the floorboard area, and also mentioned that when they try to accelerate the unit does not move as fast as it should.
The model / serial is a GCX15E / GX127E-0992-9355KF.
What I found when I arrived is a loud tinny clanking sound from the transmission bell housing area. I checked the flex plate and cannot find any cracks in it at all. However I started using my stethoscope to isolate the noise and it appears the loudest when I probe the external oil pipe coming from just behind the transmission oil filter, on top of the transmission. You can actually feel the clanking on this pipe with your hand.
I removed the transmission oil filter and the valve behind it and found no problems there. The unit does seem sluggish to move when accelerating.
When I push the inching pedal down and release it , well it sort of quiets the noise down but it gets louder again in a few seconds.
Was wondering if anyone has run into this problem.
Thanks everyone, and if I can give any more info please let me know.

Hi, I will pull the numbers off the transmission and report back.
I've personally never pulled a trans on this model.
Any thoughts on how many hours to get it out?
I'm assuming that the easiest way is pull the mast and then trans vs removing the engine.
Thanks again.
The hr500 transaxle has the chain in it. Do you have any numbers of the transmission? Email may be helpful.
Is there a pump mounted on the back side of the transmission? If there is does it have pipes going to the transmission? You may want to pull the pump out and see if there is any play in drive gear. That gear is driven by a chain that goes around the torque converter. I don't know how common it is but the truck is old and I have seen the chains get play in them.
Is that common for this model to need torque converter replacement?
Thanks guys!
Sounds like the torque converter is failing. Some Hysters have a pump chain in the bell housing but not Clarks.
If memory serves me right there is a chain that dirves the pum on the back of the converter. In order to access you have to pull the transmission.
