Hey Sajeev,

I hate the upsell that happens at places like Jiffy Lube, NTB, etc., and one service they seem hell-bent on pushing on everyone is the transmission flush.

I have looked at the service intervals of various vehicles and a lot of them never specify a transmission flush. I’ve read on the internet that it can even be bad for your transmission if it isn’t needed. I don’t doubt there is a finite life for the tranny fluid, but I would just like to hear your and the B&B’s take on the matter.
