Hi guys ...need a little help with diagnosing a problem on my truck ... First issue is reverse ... When truck is first started and I move shifter into reverse it goes right in ...but after an hour of driving when I put in reverse there is a delay ..but then goes in ..never slips ...now in drive it shifts fine but sometimes I get a delay or flare in 3rd but that matters on throttle effort...codes I pulled from teams are as follows :po562 system low voltage ...po602 tcm not programmed and po603 ..keep alive memory error ...oh one more but don't have code number forgot it at work .. But it had to go with internal trans temp ... I also have the dreaded po0011 but no engine light is on ... Oil pressure is 20psi at idle and 55 at 2500-3000rpm ...truck has 190k on it and was well maintained ... My boss was original owner and I recently bought it off him ..,run full synthetic since new ..any info would be greatly appreciated ... Thanks Vinny
