RTV seals, it's labor intensive to clean. It all has to be scrapped each time the trans is serviced. Mazda tried to seal it for life. LOLThere can't be anything wrong with RTV if that is that Mazda uses and calls for.

IF the RTV is removed, an important step, then a gasket will work. I'll be cussing a scraping at the 30K mi mark and installing a gasket.
"If Mazda uses it" I'd still be using those boat anchor wheels, crap tires, struts, springs, sway bars, bushings and dusting/squeaking front brake pads....
BUT for those who want to go by the BOOK, RTV is your friend....
RTV will work "great" too....scrape, scrape!I like the stock struts on my Mazda 6! The rears are still original and work great!
Yeah, me too.I've heard from two different sources to use RTV (gasket paste), not a pan gasket. I'm kind of lost now.
Have you hear the gasket is leaking ATF?Yeah, me too.
Here are two trans gaskets I use. The one on the left is for a 48re. It has NEVER leakes. The reusable gasket on the right fits a Nag1 transmission pan. It does not leak.
@AL Cx5 --
Do you have a particular brand name/model of gasket you use? The 48RE transmission isn't on the Mazdas, but perhaps they make a Mazda CX-5 variant.
Yeah if I do end up trying this myself, I am inclined to try the gasket myself and since I plan to own this car long-term still, make it easy for any future pan drops.Great thread! I never noticed a change in transmission behavior on my old ‘13 2.0L. It performed great it’s whole life when I did 3 drain and fills at 50k miles, and 3 drain and fills with a pan drop and filter change at 100k miles. I used RTV to reseal the pan without issue. I didn’t plan to drop the pan again.
Now that I have the 2.5T, I’ll likely drop the pan and replace the filter at 30k miles with a single drain and fill of the fluid. I’ll use a gasket on the new CX-5 vs RTV. Will likely do subsequent drain and fills at 30k miles, maybe a pan drop every 60k miles. Gasket will be useful for that. Scraping and cleaning the pan mating surfaces is a PITA and I don’t care for popping a RTV pan off the transmission. Have to be really careful not to gouge or pry at the transmission body, aluminum is soft! : )

You’ve done some cool stuff souping up that CX-5 in a short time though!It's great to hear from a long term Mazda owner. I'm still a newbie...
I just completed a trans service on my 48RE at 280K miles. Replace ATF, filter and adjust the front and rear bands. It's a very old school trans. I do this every 30K miles. One of the pan SS socket bolt head stripped and was a major PITA to get off. I orders 3 sets of bolts yesterday, When they arrive, I'll replace all of the bolts and have 2 spare sets for the 310,000 and 340,000 mil services.
I'll replace the CX5 trans pan bolts too after the above encounter! I'm guessing RTV will be in the threads.
IF anyone knows the trans pan bolt size, please post. McMaster Carr is our friend! Amazon "suggests" these bolts are M8 1.25 x 20mm. The threads in the pic look like poor quality. I'll buy from McMaster Carr.
