Tranny Failure...help
 

Well...somethings up with my tranny. Trans. Failsafe Prog popped up.
Was driving back from roadtrip...everything was fine on the highway....then got off the highway (stop go traffic) and noticed tranny acted abit weird, when i come to a full stop, it kinda jerks...did it a few times....then we got back onto the highway driving normal without any issues and then heard a funny sound and the Trans Failsafe Prog. came on and i think this is the limp mode. Its dragging and when i drive off the stoplight, feels like its in 3rd gear.

Any ideas?

Damn dealer is closed tomorrow, so i'm gonna take it in on Tuesday...but wanna check with yall first....is it still safe to drive around in this 'limp' mode?

I have the Peake tool...but not sure where can i plug it in the car to pull codes?

thanks

Try disconnecting the battery for 20 minutes and then reconnecting it. It's possible that a simple reset will clear things. If not then it's off to the dealer.

:goodluck:

Damn! Didn't you just pick that puppy up?

yup picked it up less than 2 weeks ago.
I'm sure CPO will cover the tranny...but i have a call in to the dealer i bought it from about my NAV, and i'm gonna bring this up...good gosh i hope the problems stop here...

otherwise, it was a BLAST driving on the highway...

tried unhooking the battery....no luck.

pulled codes...
with ignition on #2 = all clear
with key off = got code E10
looking it up now

i looked under the hood, engine oil level is fine. Saw some blue fluid (coolant spots around the coolant reservoir and back abit)
will wait till it cools off to check coolant level.

But now as soon as i start the car the Trans Failsafe Prog light is on instantly.

guess its the dealer now...

Was it raining??????

yes....raining for 2 days straight....what does it have to do with it?

figured out i didnt pull the code right (hence E10) will do it again tomorrow)

checked coolant level....seems fine (not sure why there's coolant spots around) but no smell of coolant. Could hear the bubbling sound when i first stopped and popped the hood

Supersteve could be right on. Why do not you check that the electronic control box did not get wet. It is worth checking

Am I the only one that had ugly visions of Adam's apples and boobs when they saw the title of this thread?

:rofl: :rofl: :rofl: :rofl:

maybe a dumb question....but where is the electronic box?
hope it stops raining tomorrow...but forecast for all next week is WET...
any way to prevent this?

If you have the 4.4 you will find the box in the engine compartment on the left side under the hood vent.

I had the very same thing happen. Water got in to the electronics box under the hood. The DME (eng controler) and the AGC (trans controler) are both in the box. The DME and AGC are very durable and SHOULDN'T need to be replaced. Pull them both out of the box and check for water, especially in the connectors. I bent the tabs out of the way on my AGC and opened the box and used a hair dryer (carefully) to dry it out. Also used the hair dryer to dry out the DME and the Eng electronics box.

You'll also need to seal the electronics box. Pull all the rubber gromments the wiring runs through from their slots in the box. Apply a liberal amount of RTV in the slots. Replace the grommets. Some RTV should sqeeze out. With the lid to the box in hand and up side down you'll see the groove that is supposed to seal the lid to the box. It's about 1/8" wide. Fill that groove with RTV also. That won't take much RTV. When you put the lid back on the box, make sure you get all four hinges together properly.

Also, your PEAK tool plugs into the OBDII plug above your left shin. You'll have to use the adapter. The tool is round the OBDII is trapazoid shaped. If the water is the problem after you dry everything off the code should (no garrantee) go away.

The E-box is right where the passenger side (LH drive) hinge for the hood mounts. It's a little bigger than a bread box. To get it open:
1. Open hood.
2. Pull then cover off the cabin air inlet. The plastic piece that runs the width of the base of the windshield. It has a bunch of 1/4 turn fasteners.
3. Under that cover you'll see an air defector. The passenger side (LH drive) outer most part lifts out. Straight up. This is to allow you to get into the box.
4. Unscrew the four 5mm allen head screws and urine (your in).

thanks a bunch. gonna try it now.

well pulled the cover off....doesnt look wet at all. (dunno if it dried out overnite)
checked the codes (correctly this time) = no codes
Drove around the block. no errors. Tried normal mode, S mode, and also running thru the manual gears...
I'm gonna go for a longer drive later on to test it out. If the error comes back on, i'll be at the dealer tomorrow...else i'll cancel my appt.

so fair assumption that some electronics did get wet?

again thanks for the valuable information...y'all have a merry xmas!!!

You need to look at the connections. Pull the connectors of the boxes and look into the connectors. If you see any water or stains in the connections on the DME or the AGC you have had water in the box.

If it happened once it will probaly happen again.

yeah gonna look at it again later this afternoon....its frikking cold out there (even in the garage)
but will goto walmart first to get some RTV
thanks
