I'm planning on having the local dealer flush and change my transmission fluid. The Aztek has 97,000km's (60,000mi) and was put in service in 2002, so it's been on the road 7 years.
I've been reading up a bit on trans. fluid flushes tonight and I've been seeing a lot of people saying that flushes can cause transmission failure. Last time I checked the fluid it was at the right level, smelled alright and was a light pinkish colour, so everything seems peachy with it. Haven't really had any driving issues either with the rare exception of the downshift from 2nd to 1st being a little harsh.
Only reason I want to change it is because I'm pretty sure it's the original and it is a 7 year old vehicle. 97,000km's is hardly 'high mileage' but should I even be considering flushing the transmission of a vehicle of this age/mileage? My wife drives a lot of highway but definitely gives the Aztek it's share of city driving as well.
Do I have anything to worry about if I have the service done?
