47re swap in older truck

Well for this whole time I didn't know the transducer was a tempature sensor. So basically put a resitor on there and got it to 1k ohms like the old tranny was and it shifted into over drive. Put the jumper back in place of the relay and put a 33 ohm resistor on the switch and the convter lock up works.


So now that, that's all figured out. My transmission is short shifting second when locked. At WOT it will shift before 2k rpm and shift very fast. In third it will shift at about 2500 rpm and like hang up for a bit or shift slow. Where do I start with that.
