Well, looks like I'm due for a rebuild soon. Been feeling a lil slippage in the 2-3 shift & a bit when downshifting from 4-3. Nothing major, but I figure I'll get the parts together before it gets any worse. Been searching here and found a reference to Jerry's Bulletproof 4r70w build, but no actual info. I did find a bunch about getting a Pell grant to pay for your trans rebuild(jk). Should I go with a full stock rebuild using all OEM parts? Or are there some aftermarket parts that would be recommended? Any secrets to better performance & longevity? Thanks in advance to any help. If you happen to just have a link to a helpful thread, please post here. Thanks again! Mike
