Hey guys. I pooched up my transmission (4r55e) and replaced it with a tranny and torque converter from a 99 explorer (I believe 5r55e). Everything bolted up and stuff and I had to swap the shifting...module? The thing on the side that the shifting cable thing attaches to.

It drives (better than the ol 4r55e) but it is definitely not perfect. I adjusted the bands but it didn't help much. I may turn the bands in a quarter turn as they may have even made them a bit worse. Here is the problems:

-When I put it in D or R (drive/reverse) it takes about 2-3 seconds to actually engage things and start going. If I put it in and gun it it just revs up like its in neutral

-2-3 shift flare (EPC solenoid I believe?)

-Other gears sometimes flare between shifts as well

-In first gear if I gun it (trying to break loose and drift...I can't resist the snowy roads) sometimes it would rev up and then drop outta gear and just rev and not spin the tires. I am not sure if it is slipping or going into neutral

Any advice guys? I kinda wanna get a CVB valve body...how much would that help?
