I had a new transmission put in 18 months ago. Now the shift indicator light (p r n d) intermittently goes out. When the light is out the car does not want to drive well put u can hear the tranny dhift. It feels like it starts out in 3rd gear. The blazer is automatic. Any help will be much appreciated

Sounds like the computer that controls the transmission.....but don't just go buy one because there is a diagnostic route.I just worked on two of those earlier this year,and the computer can drive you crazy.92 is pre OBD 2 or OBD anything,codes are pulled from the car manually.Passenger side interior,front kick panel.Remove the kick panel,locate BLUE colored TWO WIRE connector.It isnt connected to anything.Take a paper clip or wire,bend in a U,insert into connector.Turn the ignition switch on,engine off.This throws the trans computer into self diagnostic mode.Count the number of times...on the dash...the "S" light flashes.This is the code number.Now you look up the code number on a code chart.If there are NO CODES,the "S" light just comes on for 2 seconds when you turn the ignition on,then the "S" light goes back out.Thats normal operation,no codes.If no codes,you are back to square one.Welcome to code diagnostics.Remove paper clip.IF,there are any codes,they must be identified on a code chart,as a diagnostic trouble code for say...the shift solenoids,is a definite solution to this problem.Honda trans's are problematic on solenoids,shift and line pressure.So,check for codes,diagnose any codes and repair them.If no codes,or codes have been repaired,and the same symptom still persists,then it's time to look at the computer,or PCM.The PCM is located either under the carpet on the passenger side front,near the firewall,or under one of the front seats.Remove the PCM,take to a clean bench,and dissasemble.Remove outer cover and look,don't touch,look for a capacitor that may have exploded.I had very similar problems on one....the gear selector indicator would indicate Park and Overdrive....AT THE SAME TIME,when actually in Overdrive,and the car would failsafe to 3rd gear.It was a bad PCM,but did not see an exploded capacitor inside that one.Good Luck...Hondas,gotta love em.

These transmissions are computer controlled, and this sounds like you have electronic problems coupled with mechanical transmission problems. I suggest you consult a transmission specialist to diagnose your problems.

Tell me something. Does it seem like the truck is in 3rd gear when you shift in D.If is it I know what it is.

Drop the pan, odds are the shift solenoid is out, its located at the front of the trans on the driver side. I'm sure your check engine light is on that will comment about the timing/shift solenoid being bad. I had the same problem with mine. The solenoid had plastic coming out of the inside. To remove it you'll find a small C clip holding it in, just take a small screw driver and pull the clip out. The part cost me like $36 from my local dealership. And its a longer solenoid. I believe its the 3-2 downshift solenoid. I do have the part number if you need it.
Testimonial: "Thank you so much. I actually thought this was the problem, but i didn't know. Thanks again!! send me the part number"
