1999 Cutlass Transmission Flush

I dont understand how you check the transmission fluid on these sealed transmissions. I love GM but they were complete **** when they designed this. Is there a sight or check plug on the side of the trasmission? The reason why I ask is because I am wanting to do a transmission flush soon and I want to know how to do it properly.

There is a inspection plug but the car has to be level. You can't use ramps or only put the front up on jack stands. Wait for spring service deals in your local paper for transmission service. It's not worth the few bucks you save doing it yourself. Some shops just use a length of see through hose and a empty old gallon jug to catch what drains out of the cooler line with the engine running. Replace the same amount as what came out plus half a quart. Remove the inspection plug and a little fluid should drip out. If not add more. There is also a vent port higher up that you can fill from (Chevy dealer said it was okay to overfill it by as much as a quart on my sisters 99 Malibu as it won't cause foaming or seal leaks and it's the first thing they do when these transmissions start acting up). Autozones online manual should show you where to find the plug and vent.

Where is the transmission dipstick located on my 2006 Pontiac G5? And what steps do I have to take to check and change it?

Alot of the newer GM model do not have transmission dipsticks anymore they are kindof a pain to check them. With the front of the car raised and supported level on a hoist or jackstands front and rear for a accurate reading from the passenger side of the vehicle look on thr back passenger side of the transmission there is a 11 mm bolt facing you, while the vehicle is running remove that bolt, transmission fluid should ran out of the hole, if it does not then you will need a friend to add from above while you watch while they add transmission fluid untill it does start running out that hole, if you look way down between the air box and the throttlebody there is a red cap down there remove the cap and the fluid there. To change the fluid I would recommend taking it to a repair facility and just having a transmission service done on it, it will save you a big headache. Transmission should be serviced around every 30,000 miles for normal driving conditions.
Good luck

Where do you check the automatic transmission fluid

Gotta love GM for taking the dipstick out of these models .There is a small plug on the passenger side of the vehicle on the transaxle just above the transmission pan. Remove this plug and start the vehicle in park if the fluid is coming out then it has and adequate amount of transmission fluid if not then the fill is on the top of the transmission under the crossover exhaust pipe its a plastic red/maroon colored cap.Please be very careful as the placement of this is right under an exhaust pipe and gets extremely hot.

On cold start up in the morning the transmission will not come out of 1st gear for a very long time! 1989 cutlass supreme sl 2.8

With a transmission there is not a lot you can do at home.Most problems are the fluid level.Start the car and fully warm it up.Move the gear selector through all the gears a few times and end in neutral.H/brake on.Now, with engine still running and in neutral,check the fluid level by removing the transmission dipstick.Clean it and reinsert it and recheck.If it is low,add some fluid through the dipstick tube.Slowly or it will run back out.I hope this helps you and this is about all you can check at home.

Change transmission fluide in 1999 Jeep Cherokee

To change the transmission fluid you drop the transmission pan should be about 16 bolts. Once that is off you will see the filter. Buy the kit from a local auto parts store and look to see what the filter looks like. Check your transmission fluid once you drain to see metallic look in it if so i would suggest a transmission flush.

How can I check my transmission fluid on my 1999 chevorlet Malibu. It will not go in to drive but it will go in reverse

To check the fluid level: It's a 4T40E. It is filled from a black or red plastic cap on top of the transmission

You will find a plug about 1.5" from the bottom of the transmission. This is the level checking plug. With the engine running, the fluid should be level with the opening. If a small amount of fluid does not run out, add a little until it does. The transmission pan should be about 110F or so when you install the level checking plug, since transmission fluid expands when it's hot.

Undocumented feature of the level-checking plug:

With the engine off, removing this plug drains about 4 quarts of fluid. So don't remove it without the engine running unless you want to remove 4 quarts. (I think it might make removing the pan a little less messy if you did remove this plug first).

this is not easy to do, I don't understand why GM ever came up with this type of tranny and many reason why I don't buy small GM vehicle. I recommend take it to the shop with a lift.

Local mechanic says they can't check fluid level

"Sealed" means there's no dip stick tube.
The Explorers and Lincoln LS have this also.
It is nothing new and you can still change/flush the fluid as usual.
A special procedure is used to check the fluid level.
Not having the dip stick tube is one less place for dirt to get into the transmission.

Can not find where to check trans fluid

Actually your car has no transmission dipstick...

There is a red fill cap on the transmission bell housing under the brake master cylinder. You'll have to look real hard to see it. There is also a bolt on the passenger side of the transmission that you remove to check the level.

You have to fill the oil from the fill cap until it runs out of the bolt hole. Don't ask me why GM did this on a lot of their cars...

I found this after a little research, I don't own any GM products so it came as a surprise to me.

Hope it helps
