The first few 2 AOD's I did back in 2000 I took the parts to my local freinds Tranny shop and they squeezed them in with the lip seal installers. I purchased an old scarred set from them the 3rd time
I since have purchased a new set for myself and have not used them. The ratty set is working fine with a little help from Mr. sandpaper.
Anyhow - $30 to install the lip seals is worth it. YOU MUST HAVE THIS TOOL TO INSTALL THE SEALS. That is a 99% rule. I have installed them without the tools, but it took for EVER and you jeprodize the integrity of teh seal.
1)TWO 6" C clamp or Large welding style vice clamps (install OD servo/rev servo/makshift spring comressor)
2) dental tool set for fine picking seals
3) jug of vasoline
4) 3 cans of brake clean
5) RAGS RAGS RAGS
6) rubber tiped air blower (make sure compresor is regulated)
7) metric tools
8) torque wrench !!!
9) Very good selection of sockets or bushing tools to remove/install bushings that need replacing. This is a good idea, but most of the time for persoanl rebuilds you might swing using the old bushings.
10)SNAPRING PLIERS !!!!
11) feeler guages.
I am sure I left out a tool, but frankly if you had all these you would be IN BUSINESS. You could almost rebuild that [puppy in your driveway. I accually have a tranny KIT that i put together in a seperate tool box that if needed to make a tranny house call, I can.
