With the almost 70F weather today in NJ, I decided to change the tranny mount (truck has 206,000 miles0. I did some research before today to review the steps. For me I wound up removing the cross beam that the bottom of the tranny mount bolts to. Each side of the frame has 4 bolts each. I also sprayed lube a few times during the week to loosen things up for today.

Loosen 8 cross frame bolts
Loosen 2 tranny mount nuts that face down under the cross member
Support tranny with jack and wood block
Try to loosen the 19mm bolts that the mount connects to the tranny
Remove the 8 cross frame bolts
Remove the bottom two nuts
Remove the cross member (not heavy)
remove the x2 19mm bolts from mount / tranny
Right side will have the exhaust mount too that is held on with the 19mm bolt
I used lots of WD-40 to clean and lube the threads / muts / bolts
Before putting in the new mount, I lubed and re-inserted the 19mm molts back in to lube the threads and clean them out for easy re-insertion with the mount in place.
Install the drive side 19MM fist to alight the mount
I had to use a wood block to move the exhaust/mount clamp closer to the mount / hole for re-install as I juggled the bolt and mount.
Reverse the order and test drive appeared to show a more solid engagement of shiflting

Clean hardware makes the job so much easier. I have an old bench grinder with a wire wheel to clean bolts and small parts. The Rat is metric and I have BMW nuts and bolts from having about 10 of them since 96. When I'm done with a car, It gets stripped. then scrapped. I have 8 mm Allen head 10 mm axle bolts holding in the starter. The transfer case and bell housing bolts are a mixed bunch too. I oil the stuff and lately have greased them to keep them from rusting. Sure, the grease attracts dirt. Now it has a hard shell that can be brushed off easily.

Here is another old time trick. To secure a nut from loosening due to vibration. Use a sharp punch and a 4 oz hammer to prick punch a few dimples around the threads at the top of the nut. I garontee you'll need two wrenches to remove the nut , but it will come and reform the threads as it loosens.

I have four cars in my driveway now. 2013 Escape, 2006.5 VW GTI, 2006 Pathfinder and the trusty old 1998 B4000. Amazing when I go under the VW, there is literally NO rusted parts ! My Escape was delivered with rusty rear knuckle assemblies on day one !

Few times per year on good weather days I'll lube most touch points / bolts / nuts / fittings... to keep things from rusting / freezing when the time comes for service or replacement. Hate when you have to undo a brake line tube and the damn tube AND fitting nut turn as one !
