How do I add transmission fluid to my 1998 jetta gt? what parts do i need?

Answer 1

Audi's use a CV (constant velocity) transmission and newer VW's as well. With the newer models the car must be running as well as being up on a hoist to change the fluid. Get a hose and a funnel and get your car off of the ground. Pull out the higher plug...you'll find one is higher than the other as one is for draining and the other for checking and filling. When you've got the top one out (1/4 inch square - a ratchet without a socket on it should work) stick your finger into it up to the first knuckle and curve it down. If the fluid is level with the opening, no fluid should be added. Otherwise put the hose into the opening and fill it to the bottom of the hole.

P.S. if audi was exactly like a VW then VW's would be a lot more expensive!!!

Answer 2

The transmission fluid used in your VW is different from other cars. They use a very highly refined synthetic mineral fluid instead of typical trans fluid. This fluid is not red, like most trans fluid, it is golden in color. You must use only the prescribed fluid, and yes, the system is sealed. If you suspect that the fluid is low, the only way to tell is to remove the speedometer speed sensor and add the new fluid here. You are probably better off if you have the system topped up at the dealership. Sometimes, they will do it for nothing. This is a very refined system. Read your owner's manual to be sure. If it were my car, I would have the filter and fluid changed at 100,000 miles anyway, even if the manual says that it doesn't need any attention. I like preventative maintenance. An ounce of prevention is worth a pound of cure. (Benjamin Franklin????).

If your Jetta is anything like my 2000 Audi A4 (auto), then it sealed transmission. It is very difficult to fill or even check. Just to check it the car has to be lifted and you have to go under the car with a flashlight. Jacking the front of the car is not good enough (because the car has to be level). Yes I hate this design. When Audi (and VW) first came out with this design, they stated that the automatic transmission oil is good for the life of the engine. Then when all these transmission problems came in to Audi, the "clarified" that the life of the engine is 100K !!! They must be out of their mind!

If you have a manual transmission, then it should be little bit easier. But you do have to get little bit dirty. There is a filler BOLT and drain BOLT on the sides of the tranmission. It is fairly large but does NOT hold anything down. You have to

(a) remove the filler bolt (possible from under the car)
(b) insert your finger and check to see if the oil is approx 1/4 to 1 inch from the hole
(c) get a LONG neck funnel and pour gear oil SLOWLY. Basically you STOP when you see oil OVERFLOW. Just remember whatever you still have in the funnel will ALL overflow on to the floor.

So as for the tools (for manual) you will need floor jacks, jack stands, hand tool (wrench), funnel.

Make sure you get gear oil from VW. I found they use many non-standard formula for much of their fluids (like the coolant).

Good Luck.

P.S. I just checked my manual and 1998 Jetta is exactly like Audi A4.

Answer 4

If your car has a transmission dipstick to measure the fluid level, you need to buy a transmission fluid fill funnell which has a very skinny neck that fits into the dipstick tube opening. Never put more than a half quart at a time because it's very easy to overfill a transmission and then there's no easy way to get the excess fluid out. Check the level when the transmission is VERY hot at idle.
