Ok, so im stumped

[The_Dealer]

well last week i decided to change the flexplate and torque converter on my rig because i was going on a 350 mile trip. i used a lower stall torque converter then stock(4.0), all brand new parts. so i replaced everything and used locktite blue, and torqued everything up right. also i have a manual lock up switch to lock up the t/c.i noticed that with the new torque converter that my lockup didnt work, but it kinda seemed like it was locked on the 3-4 shift. i checked all of my wires to my switch and everything is good. what could be wrong?

also my valves ticked like crazy, so when i got to my destination my stepdad helped me get them back in spec, and holy crap was it quiet. we ran through everything 3 times to make sure the tolerances were right.

also before i changed my flexplate out my starter was grinding everytime i started her up, and when i got finished with everything the starter was normal. well now its grinding on startup again and im getting a rattleing noise from the bellhousing area. fluid in trans is spot on, and everything is still tight...any ideas on what it could be? it seems to be only noticable at idle, mainly in park. what should i check out?

I don't know much about A/T's....did you buy a lock-out style torque converter? Maybe you need to keep the lock-out turned off until you reach highway speed?

Remove the flywheell dustcover & eyeball/yank on everything to check for looseness

Add a .010" shim between the starter & engine...see if that helps with the grinding...

When your starter is grinding this is MOST LIKELY a bad starter bendix or flywheel combination/teeth worn down, not sure about your rattling but I had a rattle and it was a rock sitting inside my metal protective cover for my cat, I bent back the tabs to remove the protective metal plate and removed the rock
