Ron Ananian, The Car Doctor - October 18, 2025 - Hour 1 - GM Transmission Shudder, Toyota ECM Failures & the Truth About ‘Lifetime’ Fluid - (855)560-9900 24/7 Hotline

This episode demystifies Technical Service Bulletins (TSBs) and why they’re not recalls. Ron breaks down GM’s 23-NA-072 low-speed TCC shudder—what “ATF degradation” really means and why a full transmission fluid exchange matters. Then: the Toyota RAV4 P0755 shift-solenoid fault and why many were cured with an updated OE ECM, not a transmission. Plus a quick diagnostic for a 1994 Chevy Blazer speedometer that dies on bumps (VSS → DRAC → cluster, use the cruise test). Practical, no-nonsense diagnostics that save parts—and wallets.
