Are you sure this isn't a problem with the fuel system on the engine? That would be the first place to check. Fuel filter or fuel rail pressure. Could be in the transmission.........and hard to tell from fluid color. Dropping the pan and checking the filter for partial plugging would be a good start on that end. Intermittent issues are the hardest to find sometimes. Please get back to me once you have checked those items and we can dig deeper if needed. All follow ups are included in our fee.
It could be any number of things, but it does sound like a transmission issue and draining the pan and inspecting the filter might give you some clues. It might be a bad disk...........a band adjuster might have broken. With it being intermittent, it is hard to tell. What is the number off the transmission or model number for that unit? Get back to me with this info and I can ask a trans expert who works next to my shop.
That is a head scratcher for sure! I have no idea where to have you look, so I will open this back up to other techs who might have experienced this on one of their rigs..............Let me know what it turns out to be! Thanks!
Discussed this with some other mechanic and they tend to think it has something to do with the pump pressure in the transmission which is electronically controlled. Not sure how you test that, but I have another transmission expert to talk to tomorrow.
My transmission mechanic wanted to know which transmission you have here..........then I can offer some possible solutions.
