One tablespoon of tranny fluid leads to $7200

I thought I would share my recent 05 CTT adventures.

I found a little oil one day on my driveway and had it inspected. In order to do a full inspection, they need to pull the tranny...and engine and front suspension ~$2K.

$50 Tranny seal did not fix it.

Discovered that there is a unobtainable broken gear on the pump that Porsche does not sell seperately, tranny mfr does not sell and no one in the country has a used one that we can find, so we have to buy a Porsche certified rebuilt one for $5200.

After installation ~ $7200 Ouch!

I wonder ... of all the great German engineers, when you design a part that you know it will fail over time, why not make it replacable?

Me too, a failed sensor in the transmission ended up with a rebuilt x-mission from Porsche!!!

That transmission is made by the Japanese company Aisin.

Tranny is ASIAN .. not german

Several manufacturer’s (including Asian and Europeans) no longer allow “field servicing” of their transmissions, particularly automatics, preferring to swap them out for a “factory rebuilt” unit. As the result, parts are very hard to find, if you can find them at all. The explanations’ for why they do this range from “specialized tooling/fixtures are required”, to “extremely tight tolerances require highly trained personnel and equipment”. Whether or not these explanations’ are total malarkey or not is obviously in the eye of the beholder, but it has made working on the transmissions nearly impossible. Recently, an out of warranty Nissan Altima with a pretty bad fluid leak in the bell housing area required a $2700 replacement transmission (parts only) because there are absolutely no parts available (other than replacement fluid) for the type of trans that was in the car.
