2006 volkswagen jetta tdi
I was wondering if anybody knows a reason why I can't swap the 2006 oa4 transmission from a 2.5 into my 2006 jetta TDI. bentley specs are identical to mine except for a change in gear ratio. They are both oa4 from the same year. stands to reason they would have the same provisions. I ask because this would open my search for a new transmission to a lot more potential $125 transmissions in junkyards that are far cheaper than other avenues like ebay. I have spent hours and hours researching and have not stumbled across this question, or an answer.
