5th Gear Swap QUESTIONS - MK5 Jetta TD
Hello,
I am looking to modify my GQQ (manual 2006 Jetta TDI) transmission's 5th gear with either a .681 or .658 gear.
From my understanding the .681 is the perfect medium for modifications; thus it is my first choice. However, since I am doing extensive highway driving, a .658 gear would be more beneficial.
My questions are as follows:
-Does the modification to .681 or .658 prevent cruise control from working?
-What exactly requires modification to the spring plate for the .658 gear? And Why?
-Does the difference in RPM, 11% and 13%, .681 and .658 respectively, produce exceptional fuel savings?
-What should I expect to see in MPG gains from the .681 and .658 swaps?
-What is the best type of method to remove the gears; either remove transmission entirely or remove front drivers wheel and pull gears off while transmission is attached?
-What is the life expectancy of these modification?
-How much labor is involved, and would a dealership complete this job?
-What is a trustworthy dealer to purchase these modification kits?
-How much overall cost would this modification require?
I know there are a lot of questions, but I did my best research in an attempt to answer these questions. Therefore, I wouldn't be inquiring about all of this if I had found it.
If anyone could answer these for me that would be much appreciated.
Thank you everyone for all of your threads and posts; I am a much more informed VW owner now from your contribution.
Cheers!
