Feels like transmission is slipping when changing gears.

Is this an automatic or manual transmission? When was the last time you changed the filter if it's an automatic? You may have a valve body problem too.

these cars have speed sensors on the side of the transmission that tell the transmission when to shift...check these ...you may have 1 or two...have them replaced....this also may have set off a check engine light....good luck

The gears inside your transmission are going bad. You are going to need to replace your transmission.

Hi,
Look on a 3000GT forum (search on Google) to find out how to read the transmission codes. I bet they are stored in the transmission computer. This will tell you what needs fixed.

Also, does sound like the shifter may be out of adjustment. Maybe a cable is broken or loose.

low fliud pressure in transmission..check levels and change fluid/filter and retry vehicle.

This will help.

Thanks.

Pretty much all the time!

D3, D4, and D5 are all just *DRIVE* like on any automatic transmission, EXCEPT
that the number next to the D is the "highest gear the automatic transmission will go into".
The Acura just gives you a choice, in case you don't want to go into a higher gear (like if it's slippery traction or a steep hill, etc.)

1 means: Manual gear. FIRST GEAR ONLY.
2 means: Manual gear. SECOND GEAR ONLY.
D3 means: Use automatic transmission, but engine will never shift above 3rd gear.
D4 means: Use automatic transmission, but engine will never shift above 4th gear.
D5 means: Use automatic transmission, but engine will never shift above 5th gear.

no you have a failed transmission on your hands, it is slipping.

COULD BE SHIFT SOLENOIDS

sounds like a shift solenoid in the trans.
