Cool Replacing the TCM on a 2003 A4 1.8T FWD

Can anyone please help with instructions on replacing the TCM on a 2003 A4 1.8T FWD CVT?

So far i understand the unit is located in the trani and it can be accessed by removing the trani oil pan and draining the trani fluid

Besides the obvious trani oil (does it need to be changed?), do i need to get anything else like a oil pan gasket or anything else before starting this job? Anything in particular to be watching for when pulling it out?

I have a friend that is a licensed mechanic and will do this for me so I can ship the damn unit to Toronto, i found a company that fixes them for 300 and sum dollars (which is way cheaper then what the dealer wants 2K plus!)

Any help or advice is much appreciated

Drain transmission fluid , remove rear transmission housing & you will find the TCM there. If you are replacing with a different unit it will need to be recoded. If you are getting yours fixed it should not have to be.
You will probably need about 5 quarts of fluid , rear housing gasket & if you want remove the lower pan , replace the filter & gasket there as well.

I have an 06 a4 fwd w/cvt and have intermittent flashing gear indicator. Runs ok with flashing but sluggish because it pretty much stays in 6th gear. I can shift in manual mode tho. Did you manage to get yours rebuilt and did that work out ok?

Yes I did fix it all under $700.

My mechanic dropped the trani, pulled the tcm out and I mailed the part to this company in Toronto that fixed it. It's really just a computer chip so it can be fixed. They charged me 350 bucks and after paying my mechanic a couple hundred in labour and 100-150 for new trani oil (trani oil is expensive), the entire job was just under 700 and the company that fixed the chip does offer a lifetime warranty on the repair.

The dealer quoted me 2 grand something and I was glad to save the money and not to fatten up the dealers pockets.

I have to dig out the exact company name and contact info.... It's was something like "BMP Manufacturing" or something like that but let me dig out the receipt and get back to you. I'm away at a cottage this weekend but will send you their full contact info on Monday.

Cheers

I'm also going through BBA. $330 and that includes shipping both ways. Hoping to do the whole thing myself for under $450.
