New Transmission Costs

There can't be anything wrong with RTV if that is that Mazda uses and calls for.

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. LOL

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....

I like the stock struts on my Mazda 6! The rears are still original and work great!

I've heard from two different sources to use RTV (gasket paste), not a pan gasket. I'm kind of lost now.

Yeah, me too.

Yeah, me too.

Have you hear the gasket is leaking ATF?

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.

My 48re is due for a 30K mi ATF change this week. I will be using the gasket on the left without any RTV. I'll torque to 120 in lbs. These bolts are easy to strip....

I found but 71 to 97 INCH #s for Mazda pans. These maybe smaller bolts than the Domestic 48re. I'll do 80 in lbs, go for a drive, get the trans warm and go for +90 INCH lbs.

@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.
