As to the encoder motor remaining fried since the TCCM “obtained corroded and shorted it out†— again, it doesn’t look likely to me. There are (off-the-top rated of my head) 7 wires concerning the TCCM along with the encoder motor. two of these are electricity (+/-) and so are FUSE secured. four of them are signal traces and the last 1 is sign ground. If the bottom wire was corroded and shorted (to what?
As I claimed into a prior poster, if you need to go into it, clear away the encoder motor from the TC and after that try out to have interaction the various travel modes — and enjoy the motor to ensure it’s going in both directions (it should arrive at a prevent in 3 distinct positions, for your a few drive modes — mark where it is when You begin to help you set it back there if all else fails!
Hopefully, In addition, it offers Other people the encouragement / self confidence to tackle Careers like this on their own!
I'll go out and acquire pics just before I go away for operate this early morning or I'll overlook all over again. I will consider to acquire a good shot of the connector that may help you Find where the wires go. No becoming sensible right here, however, you *really should* be capable of see where they go… because there'll be a gap where the wire ought to go.
I might advocate owning it looked at by a tranny store. The key reason why I propose That is, if it is the challenge I describe, the gears are literally rubbing the aspect with the transfer scenario — and they'll put on by way of, properly triggering a whole lot a lot more problems than where you’re at now Home Page (ie. entire replacement on the TC).
PS – the flashing swap lights reveal the procedure is attempting to talk to the remainder of the procedure. When it stops, it means it could not communicate with Component of the program.
I, myself, don’t know of any vacuum Positioned for the transfer circumstance, but I'll consider to discover in your case (I have a transmission shop in the spouse and children — I just named, even so the knowledgable just one is not nevertheless in). The TC is rather near the front in the auto — are you presently guaranteed the vacuum is just not coming through the firewall spot?
Reading your very first views on it, and I’d have to say I agree with you. Does the 4Hi gentle appear on if you initially flip the key into the ON placement without the need of seeking to get started the car or truck?
So, devoid of bodily removing the encoder motor module and manually shifting the Transfer Scenario into 2Hi, regrettably, it’s stuck in 4WD until eventually you may get it to your mechanic.
Up to date twelve/twelve/07 – I just wished to incorporate to this write-up which the TCCM has two relays in that Management the particular switching on the encoder motor — you that is definitely what you listen to “clicking†once you test to have interaction the 4WD method.
Nevertheless, immediately after actively playing around some additional, I found that there was a foul vacuum swap on top of the transmission behind the transfer case. (I are actually trying to publish pictures.. however it isn’t allowing me.) — see under!
really should alert you that there are three risks associated with set-equipment bicycles that are not a dilemma with freewheel bicycles. Utilized and preserved thoroughly, fixed equipment bicycles can be as Harmless as any, but you have to be mindful of the three Hazard areas:
You may buy a ready-designed mounted-equipment highway bicycle, but I've an in depth short article on Preset Gear Conversions that can assist you Construct your very own.
Argggg.. Could or not it's the cold? It's been below freezing for two months now also to compound the issue I don't have any heat both within the vehicle.
