M & S lights flashing
#11
I have not seen the inside of one of these, but because of the position on the side of the tranny when internals are cleaned up might want to put some vaseline around them, to help keep water out of contacts, or dielectric grease.
I would wonder is this sort of thing could be sprayed with some rubber undercoating spray on the outside, when guys are under their trucks, to fight off water ingress....

I was thinking about doing something like what you stated. The new switches use to go for around $300 dollars a couple of years ago. Now they are $640. The $125 one is either used or refurbished. I rather try to clean and fix mine than buying a used on. I will also see if I can reroute the A/C drain. I hope that it is just a false contact at the plug that just needs some contact cleaner but I doubt it.

this is the best write up i have seen. i have done this procedure myself. i cleaned up where the gasket was and used a waterproof adhesive gasket maker...
so u get an idea on how filthy it is in there here is mine after i drilled it open.

Hard to tell from the close ups, but it looks like wires may be attached by the type of connector that cuts through the insulation, rather than a crimp on lug. If that is the case, might consider stripping and soldering those as well. If you are cleaning up the contacts, don't use a small file, it will remove too much plating.

It is most likely NOT the XYZ switch.
A blinking M and S light alone will indicate low voltage / battery under proper voltage. The condition may be intermittent.
Replace or have your alternator and battery tested.
IF it is the XYZ switch failing as a result of drainage from the AC drains, the gear display will also show a capital D with a slash through it, and it will also be flashing in conjunction with the M and S lights.
Don't replace the XYZ switch if you don't have to. This is just from my personal experiences with the same flashing lights.

A blinking M & S can be other things as well, there are a number of codes that trigger limp home modes:
from the RAVE:

Time for tranny fluid and filter change?
from the RAVE:
If a fault is detected, the EAT ECU immediately stores a fault code and the values of three operating parameters
associated with the fault. Depending on the fault, there are four possible effects:
associated with the fault. Depending on the fault, there are four possible effects:
l
The fault has little effect on gearbox operation or vehicle emissions. The driver will probably not notice any
change and the warning lamps remain extinguished.
l
The fault has little effect on gearbox operation but may effect vehicle emissions. On NAS vehicles, if the fault is
detected on a second consecutive drive cycle, the MIL illuminates.
l
All gears are available but kickdown does not function. The sport and manual warning lamps flash. The MIL
remains extinguished.
l
Limp home mode is selected and vehicle performance is greatly reduced. The sport and manual warning lamps
flash. In all markets, if the fault is detected on a second consecutive drive cycle, the MIL illuminates.

Of course, being an over-computerized rolling tea kettle, good alternator and up to snuff battery can cure a lot of gremlins. Code list for auto trans attached, notice last column, which shows when M&S lights will be triggered by the tranny, but there could be others...

when my xyz failed there was no slash thru the indicator.
