Unfortunately, I'm having sort of same problem and need help on this one also. Don't have code, but was told by previous owner that the O/D flashing and code it presented said gears not shifting (duh) - AMMCO told him it needed to be rebuilt. '98 SE Sport, 184K, CD4E. Fluid looks good, not burnt or discolored (changed recently), etc. No shift into o/d, no upshift under hard acceleration, or no upshift when you stand on it for passing gear. If you drive like an old lady, she shifts around 3k-3.5k rpm. Also have Cat insufficient codes, both banks and the lean fuel code (O2 or air leak). I've read through the archives and could be anything from TSS (possible VSS on yours if speedo doesn't work)(My speedo still works)to if PCU can't achieve closed loop the O/D won't work(from archives). (In my case due to the insufficient cat code) and MSPLS (neutral safety switch). Look forward to some help. Thanks



It does sound like rebuild time....
