Final drive
Explanation:
I work at VW as a translator, and we use final drive for Achsgetriebe. Vorderachsgetriebe is front final drive, and Hinterachstgetriebe is rear final drive.

The link I listed below is for purchasing a VW repair manual in English, "Final drive" is listed under "Transmissions covered".

transaxle


Explanation:
Particularly with Volkswagen, what we might call "transmission" is often referred to as "transaxle" (see links below).

http://www.geocities.com/vwresource/transaxle.html#transaxle
To begin with the basics: what most people refer to an the "transmission" in a VW is actually a "transaxle." A transaxle is used in front-wheel drive and rear-engine, rear-wheel drive vehicles such as the aircooled Volkswagen. Transaxles incorporate both a transmission and a differential into a single unit.

Da möchte ich Dir auch recht geben, aber vergiss bitte nicht TVR. Leicht und kräftig mit einem der zwei besten Sportwagenkonzepte die auch Ferrari so umsetzt (1.Frontmittelmotor in Transaxle-Bauweise(Motor hinter Vorderachse, Getriebe mit Hinterachse Verblockt)2.Heckmittelmotor)siehe http://www.tvrdeutschland.de/.

Axle drive


Explanation:
This is the accepted term for 'Achsgetriebe' in the automotive industry.

Here's a Motor Trend web reference to "axle drive":

Here's another one from Edmunds:

http://www.edmunds.com/insideline/do/Drives/FirstDrives/arti...

Maybe "axle drive" and "axle drive unit" are supplanting "transaxle" as a more generic term?

"Transaxle" refers specifically to a combination of transmission, differential and drive axle. Maybe it doesn't really address many contemporary drive systems"? It seems that the Germans are driving innovation (and terminology) here, not the Americans or British.

Where the whole "transaxle" argument falls apart is in the case of all-wheel drive. Here is a diagram of an all-wheel drive system showing the "Vorderachsgetriebe" (VAG) and "Hinterachsgetriebe" (HAG) in an all-wheel drive system:

http://www.zawm.be/kfz/Texte/Allradantrieb.pdf

There's no way you can call the VAG AND the HAG "transaxles"; in fact neither one is integral to the transmission (Schaltgetriebe), which is the requirement for a transaxle (SAE Glossary: Transaxle = "A transmission which provides differential output", i.e. a transmission with integral differential).

Note that the VAG has no differential, while the HAG has a "Sperrdifferential". As in this diagram, both Pons and ZF make a clear distinction between the "Achsgetrieben" which are the drive units at the axles (with gears & pinions), and the "Differential" which adjusts the torque to individual wheels.

--------------------------------------------------

In the literature the distinction between "axle drive" and "differential" is often blurred. This might be the case in your context too, since I see "VAG und HAG als offenes Differential", although I'm certain that the VAG and HAG include the "gear & pinion" that define the "axle drive", and the "als" may be more of a "mit". Another term used in this context is "final drive" (= "Achsantrieb" per Schmitt/Pons).

I still recommend "Axle drive" to reduce the confusion though!

neutral  Ken Cox: maybe, but I'd be more convinced by references to US or UK sites\\You may think I'm splitting hairs, but I read that as 'front-axle drive' (like lots of other hits for front/rear/single/dual-axle drive, etc.) Pity that hyphens have gone out of fashion.

  -> How would you propose translating "Hinterachsgetriebe"? "Rear transaxle"? Highly questionable. My goal is to convince you, Ken. See my recent notes.

Explanation:
In response to Robert's persistence: OK, I concede that 'transaxle' is not right here. However, I have slightly different suggestion:

(front/rear) (axle) drive unit (aka 'final drive unit').

See e.g.:

Final Drive Unit

The FDU houses the speed splitting differential and provides the directional translation from longitudinal to transverse. It also provides the ratio adjustment between gearbox output and wheel speed.

Torque Management

Torque produced by the vehicle engine is transferred to the road wheels via propshafts, final drive units and sideshafts. Under some operating conditions, such as in snow, ice, mud and loose surfaces, one wheel can loose traction. If traction is lost the wheel spins and the vehicle is unable to move or temporarily loses momentum. A torque management device is one that senses when a wheel slips and reroutes torque to the wheels that have more traction. Torque management devices can be located in final drives to control slip across an axle and/or centrally on four-wheel drive vehicles to control slip between front and rear wheels. Vehicle mobility and handling are greatly enhanced by the best use of individual wheel traction.

agree  rjbemben: Ken, the only reason I was persistent is because you were "Agree" on transaxle. I think we're gradually getting to the bottom of this (whew!).

agree  rjbemben: That's what I finally concluded too. Good to hear from someone at VW!

neutral  Herbert Fipke: Difficult to differ... it's a final drive only if it is a differential. If there are shiftable gears in it, it's a gearbox (front) or a transaxle (rear). A fuzzy term would be "drive train" which covers it all.
