09G Pump 2006-2013

If your 2006-2013 Jetta, Passat, Golf, Rabbit, Beetle or Tiguan with the six-speed automatic is slow to pick up Drive or Reverse, slips in every gear once it is hot, or makes a whine that rises and falls with engine speed, the oil pump is one of the first parts to rule in or out. This is a remanufactured front pump for the 09G, the Volkswagen name for the Aisin TF-60SN, matched to the 2006-2013 production years.

What the pump does in a 09G

The 09G pump sits at the front of the case directly behind the torque converter. The converter's impeller hub has drive slots that engage the pump gear, so the pump turns any time the engine runs. Everything hydraulic in the unit starts here. Pump output goes to the pressure regulator, then on to converter charge, the cooler and the lube circuit, which Sonnax describes as one series circuit. The 09G valve body then uses linear solenoids to trim that line pressure and feed each clutch, but the solenoids can only work with the volume the pump gives them. A worn pump cannot be tuned around with software or a new solenoid set.

The housing in the photo also carries the stator support shaft and the sealing ring grooves that feed the forward clutch circuits, so gouged ring lands or a worn bushing on a tired pump leak pressure even when the gears themselves still look usable.

Symptoms of a worn 09G pump

• Delayed engagement into Drive and Reverse, worst after the car has been driven and the fluid is thin.
• Slipping or flare in every gear, not just one shift, which points to supply rather than a single clutch.
• A whine that follows engine RPM in Park and Neutral as well as in gear.
• Fluid running hot or smelling burnt, because a weak pump also starves converter charge and cooler flow.
• Ratio or slip faults set by the transmission control module after repeated slipping.
• Bronze or aluminum flake on the pan magnet from bushing and gear wear.

How to confirm the pump before you buy

Check the fluid level the correct way first. The 09G has no dipstick, and a low level gives the same slow engagement as a worn pump. Look at the fluid against our ATF color and smell chart; dark, burnt fluid with metal in the pan backs up a pump or converter problem. If the level is right, a line pressure check that stays low in every range is the clearest sign of a supply issue. Pressure that is low in only one range points to a clutch circuit or valve body bore instead. Our guide to Aisin slipping under load walks through separating a pump, solenoid and clutch fault on these Aisin six-speeds.

Once the unit is out, inspect the converter hub. Worn drive slots or a scored hub journal will chew up a new pump bushing, so the converter needs attention at the same time.

Fitment

This pump is listed for 09G transmissions built 2006-2013. That covers the front-drive VW Jetta, Golf and Rabbit with the 2.5L, the Passat and New Beetle, the 2009-2013 Tiguan, and related Audi A3 applications from those years. Aisin and VW revised internal parts during the 09G run, so the model year alone is not proof. Compare the bolt pattern, the stator shaft spline and the number of sealing ring grooves against the photo, or send us your year and VIN and we will check it before it ships. If your car is a 2003-2005 model, see the 2003 09G pump listing instead. More parts for this unit are on our Aisin transmission parts page.

Install notes

• Fit a new front seal and pump O-ring, and replace the sealing rings on the stator shaft if they are not already new.
• Lubricate the pump gears and bushing with clean ATF before installation so it primes on the first start.
• Torque the pump bolts evenly in a cross pattern so the housing seats flat without binding the gears.
• Inspect or replace the converter, and flush the cooler, because the debris that wore the old pump is still in those circuits.
• Change the filter and pan gasket with the 09G filter and gasket kit.
• Fill with VW-approved 09G ATF and set the level at the check plug at the specified temperature; the 09G service kit with 6 liters of ATF covers that fill.
• Reset the shift adaptations with a scan tool and road test, as covered in our adaptive relearn guide.

If the pump failed from heat and debris, the clutches probably took damage too. In that case a full 09G master rebuild kit on the bench costs less than pulling the transmission twice.

Will this pump fit my 2011 Jetta 2.5L automatic?

The 2.5L Jetta with the six-speed automatic uses the 09G, and 2011 falls inside this pump's 2006-2013 range. Because internal parts were revised during the run, compare the photo with your old pump or send your VIN and we will confirm it.

How do I know it is the pump and not the solenoids?

A worn pump causes low pressure in every range and a whine that follows engine RPM. A solenoid or valve body problem usually affects certain shifts or gets worse only when hot. A line pressure check that is low everywhere points to the pump.

Do I need to replace the torque converter too?

Inspect it at minimum. The converter hub drives the pump through slots, and a worn hub or scored journal will damage a new pump bushing. Contamination from a failed pump also stays inside the converter.

What fluid does the 09G take after the pump is installed?

Use VW-approved 09G ATF. The 09G has no dipstick, so the level is set at the check plug with the engine running and the fluid at the specified temperature.

Does the transmission need a relearn after a pump replacement?

Yes. Reset the adaptations with a scan tool and drive through every gear so the transmission control module relearns clutch fill times on the repaired unit.
