Try fixing the problem of the downshift button Active Code first. See if the -13 Codes change at all.
You have to fix it either way because the transmission will not shift correctly.
FIRST I need to replace the switch. 158-5626......seems to be missing some parts in the handle!!LOL
Machine is 2 hours away........one way........from me. I try and get all of my ducks in a row before heading out to them.
A couple of odd things about this machine. So it's 24 years old, but only has 4k hours on it?? Weird.
Machine came from Canada, then sold via auction (Iron Planet) here in US last year. Then my customer bought it.
Last week I had CAT run the serial number looking for oil sample history via SOS. At first they didn't find anything. I had explained on my first call that it was a Canadian machine and asked whether SOS had a US division and Canada was seperate. They didn't know. Second round of phone calls..........YES, SOS Canada is separate from US. Got hits on previous sample history. So repair history and oil sample history show 67,299H from March 18th, 2020.
I had talked with the dealer in Quebec, Canada who sold this machine when new. They had an ECM snapshot from 2020 showing the engine ECM had 3700 +/- H on it. The dealer and I tried to figure it out..........no records of rebuild, major work, etc. The machine looked really good for that age. Hoses looked to be original and in good shape, not hard and cracked. Pedal wear from daily operations was not significant.........certainly doesn't show wear on the pedals or floor mat for 67k H. Overall appearance of machine DOES NOT indicate 67k H on it. Either somebody dropped the decimal point on the hour meter and it has 6729.9 hours.........or they recorded Kilometers instead of hours?? But that would be something like 30+ Kilometers per hour going by the trans ECM hours recorded.
The engine ECM was replaced either before auction or after. But hours not set to match old ECM, I can only go off trans ECM for hours. New ECM showing 118H at present.
So when I had plugged into this back in December.....I had no Logged or Active codes shown on ET. And I forgotten to do a Status report.
Logged Diagnostic Codes [Diagnostic Clock = 3796 hours] - Transmission 950
Code Description Occ. First Last
621- 3 Downshift Switch : Voltage Above Normal 1 61628 61628
So trans ECM logged codes........Diagnostic clock shows 3796H..........one logged code 621-3 Downshift switch
First 61628
Last 61628
Every other logged code references the current hours on the trans ECM.
So, oh wise sage.........any epiphanies to share on how and why some codes say 61k H and others say 3796H??
And, as always; THANK YOU SO VERY MUCH WITH ALL YOUR HELP!! From me and everyone else you help out.
