I believe BMW used to use Getrag manual boxes yeard ago,as did Vauxhall occasionally,could that be the link your thinking off Chris.
Btw,the manual getrag box was a great box and pretty strong imo.

From a flexibility perspective then yes they are, torque converters are truely clever devices.

I really should scan a few pics of the internals of one in and describe how they work some time.

Fairly strong boxes the getrags, shifts are a bit notchy though and repair is challenging!

I think I've seen it a few months back IIRC.

Just so happened that I had the PDF above open!

What was the model of the 5 Speed auto that was fitted to some of the late (diesel I think?) models?
Dont think they were available in the uk though? :-/

if DSG could be made as reliable as a manual, i would have one over a 430L family box all rather day long. If it does not impress there "Must" be something wrong. Clonkey? Nothing wrong with it? You want a broke one in that case, as all others must be, clearly.

Lol, I didn't understand a word of that......been on the beer?

Ar25/35. Are they not related to the BMW 430L auto boxs(or what ever they are called)?  Anyway, would have a DSG if reliable over an Omega box any day. To imply DSG are "Clonkey" then obviously there is something wrong with that partitlar example. Driven 3 DSG'S  now, all very smooth. Def no clonks.

To answer your question, no, no beer.....

..... sits back and waits to be blindly told the opposite by another member, and gets ready to congratulate him as a winner, and to go forward to the first heat of his chosen sport (master mind?) for the special olympicis. :-) night all.

Of course they are smooth when working, this is due to what they do with the engine. They vary the engine revs (up for a down change) and back off the torque (for an upchange).

There achilles heal is that they learn the driver (more important with a clutch based setup) so you can get rough changing when two opposing driving styles use the car after each other whilst the new driving style is learnt.

The 4L30E is NOT a BMW box, its a GM unit and the basic design goes back to the 70's (as a 3 speed) which then had an additonal section bolted in (hence the seperate small sump at the front) and a box of electronics added to bring it upto date. This does use a basic retard function to smooth gear changes.

More modern auto boxes are as smooth (if not smoother) than a DSG as they use the same engine control (which is the bit that makes the change smooth) during a shift.

Note, the VAG DSG is a Getrag unit.....not a VAG design

I've always wondered that! I know know!   

Anyway - Autos are still better 

That's why when the gearbox go into limp, it stops in 3rd & won't go up to 4th
