Is your Ford or GM 10-speed transmission shifting hard, flaring between gears, or acting unpredictably? Ron explains why these transmissions commonly develop problems, what should be checked before replacing a transmission, and why software updates, fluid condition, and valve body issues can all play a role.

Ron also answers questions about a high-mileage Acura RDX transmission, discusses whether it's smarter to repair or replace an older vehicle, explains what "Top Tier" gasoline really means and whether it's worth the extra money, and shares why preventative maintenance is still the least expensive repair you'll ever buy.

Plus, listener calls on diesel trucks, transmission diagnostics, and keeping high-mileage vehicles on the road—because good mechanics aren't expensive... they're priceless.

Ron Ananian, The Car Doctor - July 18, 2026 - Hour 2 - Ford's 10-Speed Transmission Problems & The Truth About Top Tier Gas

https://api.omny.fm/orgs/e73c998e-6e60-432f-8610-ae210140c5b1/clips/a3c5046a-dd2b-437b-8145-b48b01596b16/transcript

From the Car Doctor archives (October 2015).

Long before software updates and vehicle programming became everyday repair procedures, Ron Ananian was explaining why the future of automotive service would depend as much on computers as wrenches.

In this classic episode, Ron sits down with Hugh Atkins of Drew Technologies to discuss J2534 programming, factory software flashing, and why independent repair shops need access to the same programming capabilities as dealerships. It's a fascinating look back at a conversation that helped predict where the automotive repair industry was headed.

Ron also welcomes Harlan Siegel of Launch Tech USA for an in-depth discussion on scan tools, bi-directional controls, and how professional diagnostics were rapidly becoming essential for every repair shop.

Also in this episode:
Should you switch an older transmission to synthetic fluid?
Understanding the Ford Focus DPS6 transmission clutch shudder.
Toyota RAV4 oil consumption concerns.
Why accurate diagnostics—not guesswork—save time, money, and unnecessary parts replacement.

Some of the technology has evolved since this program originally aired, but the principles of proper diagnostics and understanding how today's vehicles work remain as important as ever.

Ron Ananian, The Car Doctor - October 17, 2015 -  Classic Car Doctor: Factory Programming Changed Auto Repair

Originally broadcast on October 17, 2015, this classic episode showcases the diagnostic philosophy that has defined Ron Ananian, The Car Doctor for more than three decades.

Ron shares two unforgettable repair stories from the R\A Automotive service bay. A 2008 Hyundai Tucson that spent three years bouncing between repair shops—and collecting unnecessary repairs—is finally fixed after one simple diagnostic test. Then a seemingly complicated no-start on a 2010 Toyota Yaris, already diagnosed elsewhere as needing an immobilizer or computer repair, turns out to be solved through careful testing, proper battery voltage, and a misplaced fuse.

Ron also welcomes Jerry Ostalecki from Gibbs Brand Lubricant, discusses scan tool technology with Drew Technologies and Launch Tech USA, and answers listener questions on a Pontiac Vibe and Toyota Matrix.

The technology may have evolved since 2015, but the lesson remains timeless: great technicians don't guess—they diagnose. It's not the scan tool that makes the mechanic. It's the mechanic that makes the scan tool.

When One Glow Plug Can Cost You an Engine

A simple check engine light on a high-mileage 2016 Chevy Silverado Duramax turns into a lesson in why experience matters. Ron shares the tense, hour-long battle to safely remove a seized glow plug without turning an $800 repair into an $18,000 engine replacement—and explains why the best technicians know when to slow down.

Also this week, Ron talks with a Honda owner wondering if a dealership's $3,300 repair recommendation is really necessary, helps diagnose a no-crank Cadillac CTS, discusses Harley-Davidson starting issues, and explains why sometimes the most valuable tool in the shop isn't a scan tool or a socket set—it's decades of experience.

It's another hour of Car Advice, Done Right.
