Hello all, I've been lurking here for a while, what a wealth of knowledge!
Have had 2 Cummins Rams in the past, but both were manuals (2001 & 2004). Just bought an '06 auto and was wondering if anyone has instructions on installing the B&M drain plug for tranny temp in the tranny pan. ie, do you drill and drain, location of hole, what size hole, reuse fluid? Also how much to refill tranny and should you stick with Mopar brand, etc.

Also, the exhaust manifold doesn't have the flat spot on top where I put my pyro thermocouple in the past. Wondering where you all are installing your probes pre-turbo on the '06. Thanks in advance for any info!
