Honda Engineering, Premium Price — Same Transmission Issues — Expert Acura transmission service since 1987. All models, all years. Free diagnostic.
Acura shares transmissions with Honda — meaning the 3rd clutch failure that plagued early 2000s Honda Accords was equally problematic in Acura TL and MDX. Modern Acura models have improved significantly, though the 9HP48 ZF nine-speed used in RDX and MDX has had documented shift quality issues.
Acura transmission work follows Honda procedures on older models and ZF procedures on newer ZF-equipped models. We handle both.
Years to watch: 1999–2004 TL and 2001–2005 MDX (BDKA 3rd clutch — same as Honda); 2009–2014 TL/MDX (input shaft wear); 2014–2019 RDX and MDX with ZF 9HP (shift quality issues).
Our technicians know these failure modes by heart — we rebuild and repair them every week.
Transmission: BDKA
Acura TL (1999–2004) and MDX (2001–2005) use the BDKA five-speed automatic with the same 3rd clutch failure as the Honda Accord B7XA. Identical failure, identical repair.
Symptoms: Loss of 3rd gear, slipping between 2nd and 4th, vibration when 3rd gear should engage, P0730 code
Transmission: CLA 6AT
2009–2014 TL and MDX six-speed develop input shaft bearing wear causing noise and eventual clutch failure.
Symptoms: Whining noise in drive, vibration under acceleration, slipping in 3rd and 5th gear, noise that increases with speed
Transmission: ZF 9HP
2014+ RDX and 2016+ MDX with ZF 9HP48 nine-speed have documented harsh shift and judder issues — particularly the 1-2 upshift when cold. Software updates exist but don't fully resolve it.
Symptoms: Harsh 1-2 shift especially when cold, judder at low speed, hesitation from stop, hunting between gears at highway speed
Transmission: SH-AWD
Acura's SH-AWD rear differential motor wears on high-mileage MDX and RL models, causing vibration and AWD warning lights.
Symptoms: Vibration from rear of vehicle during AWD engagement, SH-AWD warning light, burning smell from rear

Start with Free Diagnostic →"Honest diagnosis, fair price, and the repair was done right. Chicago Transmission has been my go-to for years. Wouldn't trust anyone else with my car."
"The free diagnostic alone was worth the trip. They found the problem fast, gave me a written estimate, and completed the work on time. Exceptional service."
"Family owned and it shows. They treated my car like it was their own. The lifetime warranty on my rebuild gives me total peace of mind. Highly recommend."
Yes — very well known. The BDKA 3rd clutch failure was one of Honda/Acura's most widespread issues. Full rebuild required: $1,600–2,100 for TL.
Start with a TCM software update (Acura may do it free if under warranty). If shifts don't improve, valve body inspection is next ($900–1,600).
Yes — we service and rebuild the SH-AWD rear differential unit. Common on high-mileage MDX.
If the MDX has under 150k miles and is otherwise in good condition, absolutely. MDX chassis and engines routinely reach 250k+ miles with maintenance.
3–4 business days, including road testing through multiple AWD engagement cycles.
Free computer diagnostic included with any Acura transmission inspection. Same-day appointments available at our Lincoln Park shop.
