914World.com _ 914World Garage _ OT: auto trans swap in VW`Mk4
Posted by: poorsche914 May 27 2017, 08:57 PM
I have posted this in two different places on VWVortex but have gotten ZERO response 
Hoping someone here will have experience with these transmissions.
My son has an '02 GTI 5-speed that needs some major work restoration work. We have located a parts car that will work perfectly - '03 GTI in same color but with an automatic transmission.
I have an '04 New Beetle Convertible with 6-speed Tiptronic (09G) that ist kaput. VB and solenoids have been tried without success - still flares into 4th and never engages. I think it is a mechanical issue that would entail tearing down the unit... something I am not equipped to do.
My question: is the 09A (5-speed tiptronic) a direct drop-in for the 09G (6-speed tiptronic)? Is it as simple as swapping the units and TCM? I do have a VAG-COM so can clear codes, etc if needed.
Sure would be nice to get two non-op VWs back on the road. Will clear up the driveway for another 914 project 
Any advice and input is much appreciated.

No idea. I imagine you would have to switch out the TCM's and at the very least reprogram the trani code in VagCom for the engine. Maybe new guage cluster?
I think your better off getting the right trani and selling your old one.
Great resource

I may be off topic, but I'd love to see a modern automatic in a 914. 
Yeah I know, sports car blasphemy... just saying.

Ive been wondering about the feasivility of a PDK from a boxster in my setup... itll bolt up... but I really dont know if the control parameters will be able to be programed right..

See if you can get this question in front of Tom w/AP Tuning in the Vortex transmission forum. They do quite a bit of trans work and may be able to get you that answer.
I do know that there are differences in the crankshaft snubs between manual and automatics. With both being electronic designs you would think they would be compatible

a Paddle shift 914 would be badass ...!!!

The problem is, an entire decade or more of VW automatics are garbage. Buying a used one would be hit or miss. Even if coming from a "known working" car - just a matter of time before it has issues.
Thanks for the response.

I have this same question posted in both the Automatic Transmission and Golf/Jetta Mk4 forums of VWVortex. After a week, no response yet. I'll keep checking.
If we end up getting the parts GTI and I find the time, I may just try swapping them and seeing what happens.
