Transmission Fluid doesn't have a cap. It's added with a small funnel to the dipstick tube.
There is no transmission fluid cap as such. The dipstick is the closest thing there is to a cap. If you need to add fluid simply pour the correct fluid down the dipstick tube.
Same place you check the level.
The transmission fluid fill cap on a 1989 Chevy school bus with a diesel engine is under the air filter. The air filter has to be removed to see it.
You remove the transmission dip stick. You will need a small funnel that will fit in the tube where the stick goes in at to check fluid level in transmission. Put fluid in there.
trasnsmission stickon the drivers side under hood, there is a red cap under exhaust pipe ontop of transmission, this is where you add fluid.
The red dip stick is where u pour it in same place its kinda weird
Alot of newer cars have a red cap on top of the transmission and you have to pull the speedometer on the transmission ( not a due it yourself check if you have a cap on top of your transmission refer to a repair shop or local oil change store.
On the top of the transmission there is a red cap. that cap comes off and you add fluid through there.
You add fluid through the dipstick tube. There is no cap like the oil.
there is RED CAP on the fill hole it will say TRANS FLUID there is a bolt on passenger side you will remove then check while running to see if fluid runs out. pain to do ..
1st of all the term is transmission fluid and 2ndly the transmission does not have a cap. The cap that you are incorrectly referring to is actually the stick you use to monitor the levels of the fluid and its housing is the mechanism you utilize to add transmission fluid if needed. Since you don't know, obviously the vehicle must be running when checking the fluid. The oil cap will say or state oil, however the transmission stick will not. hope I've been some help to you. Good luck.
