I got my sls back on the road after a suspension rebuild and two days later It starts giving me transmission problems. 1st and 2nd gear work fine, when it shifts into 3rd it stays in gear for a while but if I let off the gas it acts like its in neutral, there is no engine braking and the rpm drops to idle, applying the gas runs it back up to engage or just free wheels like its in neutral, it never makes it into over drive at all. I've done a bit of research (caddyinfo archives) and it looks like the shift solenoids ($300 fix) but my local tranny guy says I'm wrong and need a total rebuild ($1200+). It has no codes showing in this condition, which seems a bit odd.
Any ideas would be welcome.
