I'm installing new G68 and G32 sensors on my VW Jetta MKIV. I believe the G68 resides below the Transmission mount bracket. I have read that I need to "lower the transmission"? I have purchased new bolts for the trans bracket. My question is how far do I need to "lower it"? I have never lowered a trans or engine so just looking for the correct process. There is a dogbone or rear-engine mount also. Will the trans lower enough to change the G68 sensor without removing the rear-dogbone bracket as well? How is the trans able to lower with the rest of the motor still mounted? Thanks!
Use a floor jack or trolley jack under the transmission. Also use a block of wood if you have the jack on the transmission's lower pan. You will see that the whole engine and transaxle assembly will tilt down somewhat with the transmission mount removed. If it is not enough to replace the sensors, raise the jack back up and take off that dogbone, then lower the whole thing again until you can get to the sensors. Be careful when getting the mounts back on, that the engine and transaxle settle down perfectly into the mounts, so you have no vibration issues.
Thank you for the help. I do have a Trolley Jack. I was wondering where I should place the jack with regard to the transmission. The car is low and the jack fits under the trans, but not with a piece of wood. I could maybe get a thinner piece, but do you think I need to put the front end up on jack stands and then suppor the trans with the wood? What is a good location to position the jack for this job?
The wood can be as thin as a small square of plywood-IF you have the jack right under the fluid pan of the transmission- that is very thin metal. To distribute the weight better so the head of the jack won't dent in the pan- that's why I said a piece of wood, but hey, plywood would distribute the weight evenly. Any place on the transmission will work-you are supporting the combined weight of that end of the engine transaxle assembly, and not that much to support it, the other mounts would keep it from falling down too far.///well, you may need the front up on blocks or stands just to get under there where you need to be. The work you are performing would be better done with the vehicle level, though, so consider jack stands or blocks at both front and rear. Keep it as low as you are comfortable with working under there. And doesn't need "perfectly level", just close to it. then you won't have any trouble lining up mounts again.
