Wrench of death?

[Smacelroy]

Now I'm not sure if this is a tranny issue or a motor is ue so I will explain. First off motor sign just came on while driving along with the wrench symbol. Although the book says "limp home mode" I felt no difference in power but the truck was sucking in a massive amount air, the tranny gadge was also non functional. I was not pulling anything nor do I drive the truck hard. Yesterday I did do an oil change and fuel filter change and red tint was found on motor filter (was mostly determined farm gas from a leading gas companies here in town but can not verify). I drove it to a friends house to let it cool down. After sitting for an hour or so truck seemed to be fine (engine light was still on, wrench was not) afteter a few minutes wrench came on, air starting to suck a massive amount and symptoms returned. Any ideas? All fluid levels are ok, tranny fluid not burnt, shifts as normal. ( did post this up in 911 but after doing so I figured I would just repost here in 6.4 section) daily driver, 2010, no mods

tranny issues usually flash the OD light

sucking massive amounts of air?? like maybe the fan clutch is locked up ??

To Be clear for others you found red tint on the fuel filter only

Yesterday I did do an oil change and fuel filter change and red tint was found on motor filter

can u get it scanned ???

I don't think anything is stuck because it will come and go (air sound). Only reason I'm thinking its a tranny issue is because the gadge stops working once it gets to a certain temperature then drops down to 0. When I first jump in and truck is cooled down the wrench is not on, tranny gadge is working, but engine light is on. Once truck warms up wrench goes on, gadge shuts off, and air starts to flow.

did the gauge thing happen at the same time as the CEL light?

IDK but the fan may be commanded by the trans temp sender so ?? it's in the trans and easy to change if it comes down to that

the harness is down there also maybe check it for looseness??

[Smacelroy]

Yes, cel light? Engine emblem was illuminated and wrench on led part of cluster. I'm assuming we're talking about the same things

[Smacelroy]

Once the wrench shows up the tranny gadge shuts off like its cold or the truck is not on

[ZMANN]

CEL = check engine light

ok then I think your Temp sender is bad or a wiring issue but that is a wild arse guess

We have the Original engineer on this Forum= Mark try the transmission section also and link to this thread

[Smacelroy]

Sorry, don't know all the lingo yet lol. But if it was just a bad sensor why would it throw so many codes, gadge off, wrench, cel, and make the truck suck so much air? ( more of a curiosity question)

[ZMANN]

Well without you pulling codes with a scanner you really are just guessing

My guess the trans temp sender is having an issue and when that happens the truck commands full fan clutch function and AKA the air rush
