won't shift from 3rd to 4th
ok so here's wat I got, my iac has been acting up for the last few weeks. well today it got bad n once I got home n put the truck in park it shot to 2k rpm at idle. i stopped at the store on my way home n when I went to leave the rpms was at bout 1500 when I shifted to reverse to back up then 1500 to shift into drive, the truck slammed into both years, right before I got home, maybe the the last 3 miles of my drive, my truck would not shift from 3rd to 4th at 45 mph. no codes were present n no cel. so I torn apart the throttle body n cleaned it n and cleaned the iac to fix my idle issue, while putting it back on the truck I used some electronics cleaner to clean the iac tps n map connectors. so I got it all back together n start the truck n idle is back perfect but now I have a cel, codes p0123 tps circuit high, and a p0740 torque converter circuit. deleted the codes n test drive the truck, drives fine but still won't shift 3rd to 4th. check fluid, it was a little low so I filled it n still the same issue. cel is back on but just the p0123 code this time. Wat did i damage in the trans n newd to fix to get it to shift from 3rd to 4th, this is a 99 ram 1500 5.2. please help I need this running so I can get to work.
