...you'll love this one!
I finally got around to changing the fluid, gasket and filter on the Beater's transaxle today. It now has 175,000 miles on the clock, and I haven't taken a look at this since buying it.
I could NOT believe what I found, ladies and gentleman: it has NEVER BEEN SERVICED!!! EVER! Who the hell drives a car 175,000 frickin' miles and never bothers to service the transaxle???
I'll tell ya, I thought that servicing the wife's truck at 140k miles was bad. This thing was horrendous inside: there was a thick, grey/black sludge on the inside of the pan that was 1/8" deep; the filter medium was black, and all internal parts showing had a black coating on them. The fluid looked okay, leading me to believe that a previous owner took it to Skippy Lube and had them do one of their amazing $69.95 'fluid-flushes', which amounts to NOTHING from what I've seen here today.
It took me 2 solid hours just to clean the pan and magnet. When I buttoned it all back up with a new filter and fresh gasket, I poured 5 quarts of Mobil One Synthetic ATF in it, fired it up, purged air from the valve body, then went for a ride.
What a difference! It now shifts much quieter, and at a slightly lower RPM than before. I no longer get a hard 'clunk' when I go from R to D. I suspect the valve body was starved for fluid because of the clogged filter medium.
Folks, any one of you out there with an automatic-transmissioned Mustang would be doing yourself a BIG favor by servicing your transmission every 25k or so, and using Mobil One Synthetic ATF is also a very good idea. I use this stuff in my GT's T-45 with great results.
I still cannot believe anyone would let a car go 175,000 miles without bothering to service the transmission. Utterly ...amazing. I see people putting on junk like pink windshield wipers, fart mufflers, ugly-ass blue headlamp bulbs, and crap like that, when their money would be FAR better spent on simple, required drivetrain maintenance.
