Re: transmission flush
Hi all, I am new to the forum as of today. I have an '01 with 300,000 Km on it, and make the transmission work pretty good for it's oil (towing and drag racing ). I was using Castrol full synthetic until it was discontinued, and now use thier DexronIII blend. I get around to draining the pan and doing a refill about every 35,000 km, and so far the oil is always bright red and clean. I was having a delayed shift problem a couple of years ago and thought I would get a flush done at the dealership in case there was some contaminants lodged in the VB ( doesn't take much). The results of the flush didn't show an visable contaminants and also didn't solve the problem. Without getting too far off topic, I actually found that after cleaning the throttle body the problem went away as the transmission also uses the second TPS for shifting. As the Throttle control motor was compensating for a dirty throttle bore, the TPS sensors were also varying. Aside from keeping the throttle clean, I will continue to just do the normal oil changes until I see a sign of contaminats in the oil which would indicate an actual transmission problem.
