Alto has introduced two new electrical products. The first (pictured above) is a valve body wiring harness for GM 8L90E eight-speed transmissions (rear-wheel drive and all-wheel drive). The harness (part no. 224507) covers model years 2015-2018. The second product (pictured above) is a circuit board for BorgWarner, Audi and Volkswagen 02E (DQ250) DSG transmissions, covering
You may have heard the term “DSG” or “DCT” being used when referring to Volkswagen/Audi transmissions. DSG, which stands for “direct shift gearbox,” is the marketing term used by VW/Audi for their dual-clutch transmission (DCT). In simple terms, this type of transmission is composed of two separate manual transmissions inside a single case, each one
Your customers may not realize what maintenance the six-speed DSG DQ250 transmission in their Volkswagen or Audi vehicle requires. Besides the transmission maintenance recommended by the vehicle manufacturer, including oil and filter changes every five years or after 35,000 miles, there are also some weak points that frequently force vehicles with this transmission into the
ZF has introduced its mechatronic service kit which bundles all the components needed for servicing mechatronics on ZF transmissions, which the company describes as a critical step in restoring the transmission to OE standards. The kit’s 19 SKUs cover a range of Audi, Land Rover, BMW and other manufacturers’ car and SUV models. In addition
Knowing your transmission’s hydraulic circuit — and solenoid circuits in particular — can be very helpful when identifying the underlying cause.
The DL501-7Q is the manufacturer’s designation of Audi’s 0B5, seven-speed, dual-clutch transmission. It’s a real beast of a transmission weighing in more than 300 pounds, which is certain to hurt your back if you do not handle it correctly. There are quite of few of these running around on the streets here in the U.S. and many more worldwide. A code set for a transmission range sensor is one reason a vehicle will find its way in for repairs. Another more common reason is shifting issues related to the double clutch drum assembly.

Do the German-model engineers care about their technicians?
Body of Evidence The 09G is an adaptive-learn transmission. The TCM can adapt the upshift and downshift pressures for each shift as well as initial engagement into drive and reverse. Whenever the transmission is rebuilt or the valve body is replaced the shift adapts should be cleared and the vehicle driven to relearn the new
I recently received a phone call from a shop that was working on a 2001 Volvo with an AW 55-50 transmission. The vehicle would not move when shifted from Park to Reverse. If the selector was first put into Drive then moved to Reverse, engagement was normal. The manual linkage was checked, confirming that the manual valve was in the reverse position.
A 2003 Audi A4 with an 01J continuously variable transmission (CVT) came to our shop. The customer complained that the vehicle was sluggish in forward and had no reverse and that this would take place only when all the lights in the gear indicator “lighted up and flashed.”
A 1997 Audi A4 Quattro 1.8L turbo (ZF 5HP19) with a complaint that the transmission lost reverse once it was warmed up.
This transmission has a history of chronic reverse problems. The vehicle was scanned with a MODIS and presented the following codes: 00652, 18010 and P1602.
The ATSG tech line frequently receives calls related to engine stall or even a partial-stalling condition that could be easily mistaken for an engine-performance problem in 1995 and later Audi/VW vehicles with the 01M transmission.
