How to correctly check the transmission fluid? on 1993 Subaru Impreza

Before checking the transmission fluid should I drive the car to warm the transmission? should it be checked cold? should the engine idle for a few minutes before checking? Should the transmission be in reverse? Should the car be running?

YOU CAN GET A MORE ACCURATE READING WHEN THE TRANNY IS HOT YOU HAVE TO CHECK IT WHILE ITS RUNNING AND BE IN PARK

Well the service person at my shop had me warm the engine at iddle. Then shut off to check tranny fluid. topped it off because it was only on the end of the dipstick. said it was good to go. Now I am concerned if it was overfilled. Can this cause my tranny to fail? Since then, When i first start driving it seems slow to go into 4th speed, after it is warm it seems ok, but sounds as if it is reving, but the rpms are not going up. Thank you, R

how long has it been since you had it serviced? if its been awhile seek a trans service or flush and they will make sure its clean and full

Not sure, am 3rd owner. Car was well maintained. Well the service person at my shop had me warm the engine at iddle. It had been there overnight, so tranny was not warm from driving when it was checked. Then shut off to check tranny fluid. topped it off because it was only on the end of the dipstick. said it was good to go. I think they decided to put in synthetic tranny fluid. Now I am concerned if it was overfilled. Can this cause my tranny to fail? Since then, When i first start driving it seems slow to go into 4th speed, after it is warm it seems ok, but sounds as if it is reving, but the rpms are not going up. now that I know how to correctly check I will check it myself. Trany fluid was pink and clear, not cloudy. I did not smell it nor did the technician at said shop. Should I have a drain and fill done? Are subarus particular on tranny fluid like Hondas are?

May be worth a trip to the local Subaru dealer (at least just once) to have normal trans maint. done there (correct fluid and level should be a given there) , just to give yourself peace-of-mind.

I'll try to explain this as best as I can. So I have a 1993 Subaru Impreza. When I'm driving the RPM's will jump up and down. I'll have it in drive going like 45 and the RPM's will be at around 2,0...
