A2 AUTOMATIC TRANSMISSION // FLAGSHIP DIAGNOSTIC
2017 V6 SEDAN
2.5L V6 · 6-SPEED AUTO · 85,000 mi · P0732 flare
Customer concern
"It slips going up hills and the engine RPM jumps between 2nd and 3rd gear under acceleration. Fluid level is full. It's been getting worse over the last couple weeks."
Pre-checks
FLUID LEVEL: Full on warm dipstick — OK FLUID COLOR: Dark red, slight burnt edge on dipstick — MARGINAL DRIVES: Forward and reverse engage normally — OK SHIFTS: Crisp 1-2, FLARE on 2-3, OK 3-4-5-6 — FAIL CODES: P0732 active, P0733 pending — FAIL
Fluid level checks out. The shift complaint is specific to 2-3. Find the failure.
Step 1 · Read the upshift
Live scan values captured through a recorded 1-2-3 upshift at moderate throttle. Watch what engine RPM does across the 2-3 shift.

Engine RPM trace · upshift
Engine spikes ~500 RPM above where it should land, then falls back.
What does the brief RPM rise during the 2-3 shift indicate?
Step 2 · Stall test
Selector in Drive, brakes firmly held, brief wide-open throttle. The stall speed tells you whether the transmission can restrain the engine the way it should.

Step 3 · Line pressure
Pressure gauge installed. Idle in Drive, then capture during a 2-3 upshift under load.
Is the hydraulic supply delivering the pressure the shift needs?

The supply side is delivering. The pressure is there to make the shift firm.
Line pressure is adequate at both idle and under load. What does this rule out, and what does it point toward?
Step 4 · Pan drop & inspection
Pan dropped, fluid drained for inspection. Examine the pan magnet, residual fluid, and filter.
Inspection findings
The pan tells the story. Friction material doesn't end up here on a healthy transmission.
The pan contains significant black/brown material coating the magnet along with metallic debris. What does this indicate?
Step 5 · Root cause
Put it together: 2-3 specific shift flare on scan data, high stall speed, adequate line pressure, and significant friction material plus metal debris in the pan.

The right repair
Transmission R&R: replace the 2-3 clutch pack and friction discs, replace the filter, and flush the cooler thoroughly — debris left in the cooler will destroy the new clutches on the first drive. Finish with an adaptive relearn. The symptoms localized to one shift, the stall and slip pointed past the hydraulics, and the pan gave direct visual confirmation. That's a contained, confident repair instead of a guessed-at rebuild.
