Default 6AT ZF Transmission malfunction in 1st gear. - 07-03-2021, 04:56 PM

I was getting very rough shifts under wot. Recently did a tranny service kit, changed my sleeves and valve body seals. New fluid etc & it was still pulling hard, very jerky. I pulled into my job on lunch and once it got to first gear the malfunction popped up & I couldnít move really at all. I checked the codes & had 4F84 (Ratio Monitoring clutch D) and 4F53 (Fault in Disengagement of converter lockup clutch). So I drained some fluid, and it didnít shift hard anymore. But it wouldnít shift changing gears manually in M mode but would appear as M5,M6 on dash. Was going to order solenoids but donít want for that to not be the problem. Or is my trannny just done ?
