No worries, all is good. I do all my transmissions the same way... 3 times is normal. My a833 overdrive in my '69 Roadrunner took me 7 times to get it right but that trans was so rare there was no information about it from Mopar except what vehicles it came in. I kept making new shims every time I took it apart and in the end the gear shifter did not even shake at idle, unheard of in a Mopar.
