Need to put transmission fluid in 85 gmc scotsdale can't find where to add it..don't want to put it in the wrong port.

Check transmission fluid levels. You may have Shift linkage problems. Usually rubber bushings completely worn out. It could also be a similar bushing problem at the shift lever piviot.

automatic or standard? Automatics have a dipstick, you use a funnel and pour it in through the dipstick tube, Standards have a bolt on the transmission you need to take out and fill it up till it can hold no more

Look for it good... it's only four ports to add fluids to...1.your engine oil
2.brake fluid
3.transmission fluid
4.radiator
It's there...usually around the right front side of the engine, under the hood. It should say it on it. "Transmission
Fluid"

Usually add about a pint. Not quite the whole bottle. (A Pint).

5 QUARTS FOR FLUID FILTER CHANGE. IF REPLACING TORQUE CONVERTER OR TRANSMISSION OVER HAUL. YOU NEED 13.8 QUARTS. WHEN YOU CHANGE FLUID AND FILTER.BESURE YOU HAVE TRANSMISSION FLUID LEVEL TO THE FULL MARK BEFORE DRIVING VECHICLE.LET ENGINE IDLE UNTIL GET WARM BUT CHECK TRANSMISSION FLUID WHILE ENGINE IDLING.IF FLUID LEVEL DROP A LITTLE ADD A LITTLE MORE TO GET FLUID LEVEL AT FULL MARK.ONCE ENGINE GET OPERATING TEMPERATURE.SHIFT TRANSMISSION THROUGH ALL GEARS TWICE ONE AT A TIME.CHECK TRANSMISSION FLUID LEVEL.SHOULD BE ON FULL MARK.DRIVE VECHICLE FEW MILES CHECK FLUID LEVEL.IF FLUID LEVEL.FULL YOU GOOD.IF STILL LOW ADD A PINT AT A TIME.ONCE FLUID LEVEL CORRECT. SHIFTING OKAY TIME PLAY.YOU GOOD TO GO.

To add the fluid you need a funnel and it gets put in your dipstick port. Add a very little at a time and keep checking until dsired amount is there. Don;t over fill it as it may cause your tranny to burn out slip or even fail to operate.

You always add transmission fluid while the car is at running temps because transmission fluid expands when it's hot.

if automatic add after you pull the dip stick, if manual trans, top where the shifter is ,a plug to add fluid, all i no that you since you didnt put automatic or manual trans, thanks hope this helps you, robert b.

It sounds to me like your transmission is not well. It's working when the fluid is cold but not as it warms up. Pull the dipstick and check your transmission fluid for color and smell. It should be pinkish and smell like oil. My guess is that it will be closer to brown than pink and have a burnt oil smell to it. It the transmission is full, check the level with the trans warm,engine running, in neutral.I'd be shopping for another transmission. If the fluid is below the add mark, you an usually buy yourself some time on the replacement by changing the trans fluid and filter.At the same time add a transmission treatment with the new oil,I've had good luck with Lucas. Hope this helps.

Yup...down the dipstick tube...Think about it...what's at the other end where the stick "reads" ...trans fluid! You could actually put your engine oil in through that tube also, but it would take forever!
