Follow up to my earlier question. I replaced transmission pump and torque convertor after removing transmission and finding the torque convertor splines that key into the transmission pump were worn completely off. Now when backhoe is working (driving) under load (moving material) the temperature gauge for the transmission goes up rapidly and looks like it will go into the red but I always back off and it immediately falls back down. any thoughts? fluids are good.

Still waiting. thanks
Hi I will try and help you with this first I have a couple questions and letting you know do not rate or accept until we are done that way you won't have to pay more then once okNow with your trans over heat most transmissions have at least one trans cooler on them usually the trans lines go through radiator for one and then when they still run hot over 220degrees then a additional one is needed when your transmission failed did you flush the cooler lines?because you had some big pieces of metal that came apart with the small particles that are normal with trans wear you may have a blockage so did you in fact flush them out?
one more thing I don't know the link to your previous question so if you can go to your last question and copy and paste so I can review it would be most helpful thanks spanky
just checking back to see if you need any thing
I did flush the transmission cooler and lines before reassembly. Additional details on the problem is that the transmission temp runs normal range while driving / digging but when digging/pushing into material I can watch the temp rise (trans working hard), if I shift it into neutral it immediately begins to fall.
OK what temperature is the trans reaching?What you are saying is completely normal as long as it does not go over 230 deg then it would be OK. If it is going over that I would first check the accuracy off the temp gauge and sensor to make sure it is accurate,also you said you flushed them out did you check them for a restriction after flushing it sounds like it was not doing it before so I would replace trans cooler. If all of a sudden it is doing some thing now that is different from before there is a problem
Temp has reached over 230 but not stayed there for long. I checked temperature sensor and is working properly. I will remove trans cooler.
It sounds like it is plugged partially witch will cause your problem to be safe I would replace it or have it done by a radiator shop because if you don't get all the pieces out, one may come out later and do major trans damage so think about the cost, they are not that expensive I would not take a chance
Hi I just noticed you gave me negative feedback I have been trying to work with you and we are not finished yet so why would you give me negative feed back do you want me to opt out so some one else can help you?spanky

sorry only read the 1st half of the instructions about rating now. No issues here I am going to pull the cooler this week and will get back to you.
Ok sorry if I came off bad that was not my intention that is exactly what the experts and company are fighting about rite now because customers feel they have to rate to move on and keep leaving neg feedback to keep discussing witch looks bad for us they are suppose to be changing system but from what Ive seen it's not good yet. but just so you know if you were to rate great service that does not mean you and I can't talk any more it just means I'm doing a good job so you can rate and continue our discution that is what they are telling us but I looked at what you see and it sounds like once you rate above neutral your done and that is not the case we can still talk back and forth until you are satisfied Again sorry for there problems spanky
Any access to removal manuals, steps for trying to clean out the cooler? cat has a new cooler listed for 1087.77 trying avoid buying a new one. Know of anyone that sells aftermarkets? thanks
Do you have a radiator shop near by they would put in a hot tank with a solution that breaks up big particles to small and can check the flow for you for under 100 bucks?
Another option would be have you ever used a turkey fryer? they have them with a big bucket I would add water and transmission flush that you can get from local auto parts and boil your cooler just make sure temp does not go over 260 degrees a thermometer comes with them and you can buy one for under 50 bucks and just use a propane tank you fuel it.Then after you are done blow out all lines that you can get to
Experience: I worked on all types of equipment semis,forklifts,farm,ect.
both good ideas thanks again.
Not a problem good luck spanky
Please rate my answer informative or better so I will get paid it will not cost you any more money you already paid but I did not get paid and won't until you rate my answer thank you spanky
