Ive got the normal D4 issue (tranny limp mode) had to change a few engine parts on my 92 ex to get the cel to go away.

well tranny is still in limp mode. shift lock works when it wants and........

if i put the key in run position with engine off. the D4 goes away or is dim after a bit... but gets bright if I hit the gas pedal.

anyone ever hear of this before? is the gas pedal connected electronically to trans or tcu?

oh and just another thing I noticed. while resetting the ecu etc again this morning. theres noise under the dash behind the cluster. it has to do with the shift lock. and heres the kicker.... if I hit brake with car not running but in run I cant get out of park but if I hit the gas there is an audible click and I can shift out of park...

any ideas?

 

Sounds like there may be some wiring issues, remove the lower dash panel and get to searching.
