93 Accord> D4 always on, wont shift, only stay in 3rd gear.

[Harvz]

My 93 Honda Accord transmission has an unusual problem.
When I start the car, the D4 indicator on the dash is always on and when I shift it to D4 it only go strait to 3rd gear. It wont shift to 1st, 2nd or 4th gear as I drive it.
The same thing happen when I shift it to D3 or 2. I already tried to replace the TCM( Transmission Control Module). It went good for only two weeks then the problem came back.

Please I need your help, anybody knows this kind stuffs. I'll apreciate your reply.

Thanks in advace!

Yes mine too I have a 93 EX with same problem. I changed my transmission fluid with HONDA fluid 3 X about 700-800 miles apart and now problem gone! Need 2.5 qts to change and cost is $4.50/qt here in NJ.
