Hello all,
Thanks for letting me join this community.

I will be starting a auto transmission swap between a 99 beetle and a donor 99 jetta. Both are 2.0 gas motors.
Looking for some incite on potential problems, and solutions.
Will I run into any ECU problems?

I also have access to the complete motor and transmission, would this be an easier swap with less issues???

Thanks for any info.

So this is an auto->auto swap? Is the Jetta a mk4 body style?

Smileybug thanks for the reply.

Yes, it is an auto to auto swap, and the build date on the jetta is 1999.
So my guess it is a mk4.

I would make sure its a mk4 car. Not sure but you could have issues if its a mk3.

Smileybug, I will double check and make sure thay are both mk4's
So lets say they are both mk4's, do you know of any issues in this swap?

I have heard that there could be a difference in gearing and/or the ECU might not recognize the the new tranny. Any thoughts?

You can check the trans code. They should both be O1M's but the actual trans code will tell you gearing and such. I don't imagine a lot of problems though. No immobilizers or anything.

Thanks for the info but double checked the build date on the jetta. It was built in 1/99. So its an mk3.

I will search for another.

You don't really need to check the build date. Its the body style that gives it away.

Does it look like this:


Or this:


The top is a mk3, bottom is mk4.

I personally have not seen the car yet. I contacted a friend who works at a bone yard and he has given me all the info. And with him being a bud, I'm getting a really good price.
Here is another idea; could I swap the complete drive train?

Again, it all matters what generation this car is. If its a mk3, the engine code is different and mounts likely are too.

I have some updated information; the donor car (99 Jetta) has a AEG motor and a ECV transmission.
The 99 Beetle is equipped with a AEG motor and a ELY transmission.
Does anyone see any issues on why this swap cannot be done?

Hey there. Sorry I cant help with your problem, but I see you are in Boothwyn. I grew up in Wilmington so I am familiar with the area. Love that Farmers Market. There is a shop in Lebanon called APTuning. They only work on VW/Audis. You may want to give them a call. They have motors and trans for sale, so they may be able to point you in the right direction. This is the only shop I will let work on my car. They did my WP/TB and I have nothing but good things to say about them.

2004NBTURBOS, thanks for the reply.
Thanks for the name of a shop, its always nice to have a few. Does this shop do custom tuning? I have used a shop in Broomall, Pa. called Genes Foreign car service. Very honest and knowledgeable. They work on VW, Audi and Honda. I generally do all work myself, but when I need some special diagnosing, I will bring it to them.
The VW in question belongs to my niece, so I want to make her uncle look good, ie; me!
