Hey guys, came here for some real world thoughts/opinions. So I took the D to the stealership yesterday for an oil change. At the end of the oil change the S/A brought me a list of recommended services and flushes that they think I should do on the vehicle. He advised of a throttle body service, brake fluid flush, power steering fluid flush, coolant flush, and diff service. The real kicker was the recommended transmission service, which he quoted me at roughly $900. He says once the vehicle hits the 100k mark I'm stuck with that fluid for the remainder of the vehicle life, as no dealer will service the transmission after it hits 100k. I'm the second owner of the vehicle, I got it at 80k, it now has 90k on it. I have the full car fax on it, it was regularly serviced at the dealership. The majority of the service entries say "Recommended maintenance performed", but nothing explicitly says that those exact services I mentioned earlier were performed. My question is are all of these services the dealer is trying to sell me on truly needed, or are maybe one or two more important than the others. I know dealers make their money by trying to sell services like such as these, so I figured I'd check here first. Thanks in advance!

I've read the same...but none of those owners or reports show long term durability..as in having driven 100K miles with it without issue..until that happens I wouldn't consider it. It could be that just adding a few qts of the Valvoline is OK and still mixes well...still...and I'm a Valvoline fan.
I agree as far as a longevity stand point goes. This or any non oem fluid might last 100,000 miles like the oem fluid can, it might not. But knowing what I know now about ZFs recommended interval change I'm not going to go as far as I did this time anyways. Especially with my driving habits ;D. Not to mention I have a TCM tune. The shifts are a bit more aggressive than before the tune.
After I finish the change out, it'll be quite some time before I add 50,000 miles to what I have now (be around 77k by the time I get to it). I don't have to commute very far anymore.
That a when I plan on doing it again.
So as a follow-up, I looked at the specs of ZF Lifeguard 8 vs Valvoline Multivehicle ATF and they are very close. Actually the Valvoline has a slightly higher VI # (Viscosity Index where higher is better).. and the pour point is very close too -42*C vs <-42*C for Valvoline.
I think Valvoline Multivehicle ATF will perform fine in the ZF trans....though the oil should turn yellow adding red to green.

I hate seeing "lifetime" on anything lubrication-wise, doesn't make sense to me.
