Josh,
Here is a redacted message from another Forum member that will give readers an idea of the costs involved:
""Clean trans, teardown to remove input pinion shafts. Teardown shafts to replace "sealed" bearings, press off gears on pinion, install new bearing. Inspect all sync's (OK). Assemble shafts clean housings, replace front housing mount. Seal up & install housing, check selector. OK."
Part nos for the replaced bearings were
99630280800 (as above) and
99630280700.
Total invoice was a little over $2.5k, which doesn't I think include trans R&R.
In addition, there may be "While You are In There" jobs like IMSB, RMS,DMF, Clutch, CV Joints,shifter cables. So the whole parts cost could exceed the used market value of the car even if you do all the labor yourself.
This could be a problem - just ask your wife !
If you wish to save the marriage - tell her this is a labor of love because the car is for her ? :-) How else can yo justify it?
