I have recently acquired two used Lionel GP-30 locos (Lionel 28215 and 28815) with TMCC from different but reliable dealers. Both locos accepted a change of assigned TMCC no., receive horn and bell commands, and change headlight ends upon reverse. BUT, both engines have trouble accepting speed commands in both directions. They inch along at best and occasionally do a jack-rabbit spurt. All other engines I have with TMCC/Legacy either factory or after-market installed seem to work fine. What might I be doing wrong?
