1st & 2nd seem fine no drive or overdrive.trans. very hot. torque converter started making squealing noise, engine running great then stalled out engine. now loud bottom end noise out of engine. could trans ruin engine? engine still runs and trany still seems fine when shifting from forward to reverse but bad bottom end knock now. Frustrated
Yes the trans can wipe out the crank bearings or the spacer behind the crank(forget what its called) it can let the flexplate move and the bolts can hit.That may be what your hearing. Does it still have good oil pressure?
SOURCE: hard shift and blinking overdrive
The blinking overdrive button is telling u that a serious fault has occurred in the electronic controls or a mechanical fault such as excess slippage is occurring.

You might want to try this if its got a kick down cable unhook it from throutle body and pull it out as far as you can and let it snap back, do this a few of times, sometimes a valve gets hung up inside valve body of trans. and won't let it shift. If that don't help you may have to pull pan to dislodge it if thats the problem. chk. the plug on trans. (Its a 4 wire white plug) with test light with key on to see if there is power down there one will be hot, thats for overdrive, now on top of intake in front throutle body there is a sending unit that looks like a temp. sending unit with a 2 wire plug on it that sends a signial down to that plug when engine gets to temp. to let it shift to overdrive. Maybe this will help, or give you some ideas.

this is a worn out transmission front pump and or forward clutch pack, u have low pressure or a internal seal is leaking and you are losing hydraulic pressure that way, that is why it sipls out of gear.

Refer to your owners manual for the recommended tranny fluid, or walk into your local dealership and talk to them there
