Transmission Service Done Before You Need A Rebuild

Transmissions don't usually fail without warning — they slip, they delay, they shift hard, they leak. Catching it early can mean a fluid flush and a solenoid. Ignoring it means a $3,500 rebuild. We service automatics, manuals, CVTs, and dual-clutch trans on every major make. Backed by the Supercanic network across Southern California.

★ How We Do It ★

Our Test, Diagnose & Repair Process

01

Pull Transmission Codes & Live Data

Modern transmissions are computer-controlled. We pull TCM (Transmission Control Module) codes, look at shift solenoid commands, line pressure, input/output shaft speeds, and torque converter slip. The transmission tells us what's wrong if you ask the right questions.

02

Inspect Fluid Condition & Level

Pink-red and clear: healthy. Dark brown, smells burnt, or has metal in it: that fluid has been telling you something for a while. We check level on a level surface at operating temperature per manufacturer procedure — many newer trans have no dipstick.

03

Road Test With Scan Tool Connected

We drive the vehicle while watching live data. When does it slip? At what gear? At what temperature? Under what load? This is how we tell a solenoid problem from a clutch pack problem from a torque converter problem.

04

Pan Drop & Internal Inspection (When Indicated)

If fluid is heavily contaminated we drop the pan, inspect the filter, look at what's stuck to the magnet. Glittery fine metal = normal wear. Chunks or shavings = internal damage. The pan tells the truth.

05

Decide: Service, Repair, Or Rebuild

If it's caught early — fluid and filter service, solenoid replacement, valve body service, or a TCM relearn may be all it needs. If clutch packs are gone, you need a rebuild or replacement. We're straight with you about which one.

06

Service, Adapt, & Re-Test

After repair we use the OE procedure to bleed and fill (many modern trans require a scan-tool fluid level procedure), perform any required adaptation/relearn, then road test through every gear and verify no codes return.

How We Get It Right

What We Use

  • Scan Tool With Transmission Module Access — TCM codes, live data, adaptation reset, solenoid commands, line pressure tests.
  • Transmission Fluid Exchanger — For complete fluid exchanges on sealed transmissions — pulls old fluid, replaces with new at the correct temperature and pressure.
  • Trans Jack — Lowering and raising 200+ lb transmissions out of FWD and AWD vehicles safely.
  • Pressure Gauge Set — For line pressure testing on older automatics — confirms pump health and valve body condition.
  • Pan Magnets & Lab Analysis Kit — We can send fluid out for analysis when needed — copper, iron, aluminum content tells the story.

What We Install

  • OE-Spec Transmission Fluid — Mercon LV, Dexron VI, ATF+4, WS, AW-1, CVT NS-3, DCT fluid — we use what your vehicle actually calls for, no universal substitutes.
  • Transmission Filters & Pan Gaskets — Internal filter on most automatics, external filter where applicable, OEM-grade gaskets.
  • Shift Solenoids & Valve Bodies — Common failure points on many late-model trans (6L80, 6F35, 6T75, ZF6HP, ZF8HP).
  • Torque Converters — When stall speed is wrong or shudder doesn't go away with fluid service.
  • Reman & Used Transmissions — From reputable suppliers with proper warranties. We don't install junkyard transmissions with no testing.

★ Common Questions ★

Frequently Asked

Should I flush my transmission?
If fluid is healthy and you're on schedule, yes — fresh fluid extends life. If fluid is already burnt and slipping, a flush can sometimes make it worse by removing the worn material that was helping the clutches grip. We inspect first.
My transmission is slipping. Can it be saved?
Sometimes. Early slipping caused by a solenoid, low fluid, or a valve body issue can be fixed without a rebuild. Slipping caused by burnt clutches usually can't. We diagnose first, then tell you straight.
How much does a transmission rebuild cost?
Range: $2,200–$4,500 depending on the vehicle. Used trans swaps are often $1,500–$3,000. We always quote multiple options.
Do you work on CVTs and dual-clutch transmissions?
Yes. Nissan/Subaru CVTs, VW DSG, Audi S-Tronic, Ford PowerShift, Honda DCT — we service them all with manufacturer-correct fluid and procedure.
My check engine light is on for a transmission code. Is that bad?
Depends on the code. P0700 is a generic 'see TCM codes' — we need to look deeper. A specific solenoid code might be a $300 fix; an internal mechanical code might be the start of a bigger problem. Diagnose first.
