01M part 2. (not as interesting as Part 1, but I promise a good one for Part 3!)
Heres 01M part 1 http://forums.tdiclub.com/showthread.php?t=248847&highlight=01m
Victim: Yellow Bug 01M
Mileage:
Complaint: Wont move and Engine vibrates
Background: This car is “Daughter” driven. Local shop diagnosed as bad trans with estimate of 3000-4000 dollars.
As I tried to drive the Bug into the shop it just barely moved. Engine was racing like crazy, car was barely drifting forward, and engine was shakin’ like a poodle crappin’ a peach pit. I gave up and we pushed it in the bay. I started thinking, “better stick in a 5 speed!” (not really!)
I scanned it and it had 00652 “Gear Monitoring Implausible” code. This simply means that the trans computer (TCM) commands a certain gear, and doesn’t “see” the ratio it should “see”. It “sees” this ratio by comparing engine rpm with output rpm, taking into account which gear the trans is in. So if the TCM commands 1st it should see 1st ratio. If TCM commands 2nd, then it should see 2nd ratio.
So in this circumstance as I was driving into the service bay, the computer was commanding 1st gear but it wasn’t seeing 1st ratio, because the trans was slipping.
Next, check the fluid level, and as some of you may have guessed, there was none. Quick fill up with correct fluid, clear code, and this baby worked like new. So where’s the fluid going? I’ll postpone the answer, for now, for dramatic effect.
So as I said earlier the car had a little vibration. I could see from under the hood the trans side of the powertrain was sagging and from underneath I could see the pendulum mount was all "cocked up" from the sagging. So I pull the breather and I see this.
Good grief! How did this happen? Notice the broken piece I set up on the harness? Here’s the mount out of the car.
The plate cover that protects the front of the trans pan had a big dent and the plate cover for the engine was broken away from the engine and bent severely.
“Daughter” hit something and didn’t bother telling Ma or Pa. Probably drove over a curb or median or maybe she went 4 wheeling. Either way she ended up with a pan that looked like this.
This was not a slow leak! Overnight it left this puddle.
But “daughter”, ma, pa and neighboring shop never saw all that because they got the Bug after the trans was empty. And of course neighboring shop, didn’t know how to check one of them “sealed” up trannies.
Moral to the story is…
Check your fluid before you condemn the trans.
Or, “Get a skid plate!”
Or as Dr. House says, “The patients always lie!”
Of course we dropped the pan to inspect. It looked ok, but fluid was a little dark.
And filter was clean too.
Trans worked good, except for minor delayed engagement which is common for high mileage.
