There is a drain plug under the transmission oil pan drain and refill from the transmission dipstick 3.5l with Dexton 3 oil.
For a 1995 manual transmission grand am, the fluid capacity is 2.0 quarts for a complete drain and refill. The fluid type is 80W90 transmission oil.
If you have the 1.9L, you have to take the speedo cable assembly out and there will be the hole to fill your transmission fluid
For automatic trans you refill the fluid thru the dipstick and for manual theres a fill hole in the tranny..
On manual transmission until oil flows out of full level hole. on most manual transmission the refill hole is the oil level. On automatic transmission if no oil shows on dipstick add a quart at a time.
if it is a automatic transmission you should change it every 15,000 miles, and if its a manual its recomeded at 30,000-45,000
gearbox is the "sealed for life" type. no oil change required.
