Glycol in trany - please advice
After a glycol test, my dealer confirmed a faulty Valeo rad and contaminated transmission fluid. I was told the fluid colour was now purple, as a result.
Based on the colour and other test data, they will decide if they would change the rad only or also change the trany and torque converter.
My concern is that they may decide to cut cost (I have the extended warranty) and not touch trany and TC, while these components may have already been damaged to certain extent.
Any advice on what I can ask or check to make sure they do what they have to?
Thanks

My 2002 C32 has exhibted similar symptoms in the past - low coolant and subsequent low coolant warning light. My dealership had checked out a few things and replaced the coolant sensor. They never came to any verdict and said to keep a close watch on it in the future......No glycol test hast been done yet.

Interesting decision to replace the sensor...
If you continue to loose coolant and you are still under warranty - absolutely insist on glycol test. If not under warranty, I would act even quicker as you want to avoid damage in transmission or torque converter.

I must have had a Monday build, knock on wood. 110k miles and running very strong. Only minor annoyances to fix up until now. I have been dreading this issue since I have an early 02 C32, but so far so good.

changing the rad is cheap insurance. by the time you realise your tranny is acting up it's an expensive fix (assuming you are out of warranty) i pd 180 for my behr rad. i replaced rad, ic pump and put 2005 clear fogs in when everything was apart.

Well I pulled my car out after being parked for the winter and took it for a spin. Sure enough the low coolant warning appears. When I examined the coolant level in the reservoir it was down to half! It was full when I parked it! I will be making an appointment to take it in Monday. I will suggest to them that it could possibly be a cracked intercooler core and also to please do a glycol test since this has been going on for bit now...........
