My TSX shifts harshly on the 1-2 upshift. What's wrong?

Solenoid A failure - very common on 5-speed Honda/Acura automatics at 100k+ miles. P0750 is the code. Solenoid replacement is $350 - 550.

Is the TSX a reliable car?

Very - the 4-cylinder TSX with 5AT is one of Honda's most durable pairings. Issues are predictable and cost-effective to fix.

How long does a TSX transmission repair take?

1 - 3 days depending on whether it's a solenoid swap or full rebuild.

What ATF does the TSX use?

Honda DW-1 - the same as all Honda/Acura automatics.

Is the V6 TSX wagon transmission different?

Yes - the V6 wagon uses the BGRA unit from the Accord V6, which has the Honda 3rd clutch susceptibility. Worth knowing if you're buying one.

Acura TSX Transmission Help for Arlington Heights Drivers

An Acura TSX transmission complaint should separate automatic shift behavior, manual clutch feel, fluid condition, pressure control, mounts, leaks, and road-test symptoms before repair pricing is discussed.

TSX owners may describe slipping, hard shifts, delayed engagement, clutch slip, vibration, or warning lights. The estimate should explain whether the issue is service, external repair, clutch, pressure control, converter, internal wear, rebuild, or replacement.

The point of the inspection is to prove whether the issue is fluid, software, pressure control, clutch, converter, mount, SH-AWD, valve body, internal wear, rebuild, or replacement work before an expensive repair is approved.

Warning Signs

When to Schedule TSX Transmission Diagnosis

These symptoms need evidence before parts are ordered. Fluid condition, codes, road-test timing, and driveline clues keep the estimate honest.

Delayed engagement, hard shift, flare, or slip
Manual clutch slip, chatter, or gear engagement complaint
Fluid leak, burnt smell, or incorrect service history
Pressure switch, solenoid, ratio, or converter clues
Repair recommendation that does not identify automatic versus manual path

Our Process

How We Diagnose the Right TSX Repair

Confirm TSX year, engine, automatic or manual transmission, mileage, and fluid or clutch history.
Scan for transmission and drivetrain codes where applicable and document live-data clues.
Inspect fluid condition, clutch feel when manual, leak points, mounts, cooler lines, axles, and road-test symptoms.
Separate service, clutch, pressure switch, converter, valve body, rebuild, used, remanufactured, and replacement options.

If the evidence points to a related system instead of the transmission itself, we explain that before recommending transmission work.

What We Help You Sort Out

A useful Acura estimate should explain what failed, what can wait, what protects the vehicle, and how the repair path compares with replacement.

Symptoms

We document when the symptom appears, whether it changes warm versus cold, and whether the complaint sounds like shift control, clutch, converter, AWD, mount, or internal wear.

Inspection

Scan data, fluid evidence, leak checks, mount inspection, road-test notes, and Acura service history keep the recommendation grounded.

FAQ

Common Questions

The cost depends on the vehicle, transmission family, SH-AWD status, parts availability, programming needs, and what testing finds. We provide a free diagnostic and written estimate before repairs begin.

Not unless the evidence supports it. We separate targeted repair, rebuild, used, remanufactured, and replacement paths before recommending the expensive option.

Yes. Text 847-393-0191 with the model, year, mileage, codes, warning text, leak history, and when the symptom happens.
