Not too long ago I had a new LS1 crate engine put in my 99 A4. My original engine was destroyed from going through deep water. Well after a few weeks one day my transmission started screwing up. As i accelerated, everything was ok until i hit about 30mph. after that rpm's would jump but my speed stayed the same. In other words after 30mph the car just neutraled, but the engine was reving. I immediately took it to a Tranny Mechanic. I ended up paying $1300 to repair it. He said 2nd and 3rd gears burned up. He also said that the tranmission looked good and it hasnt been abused. That lasted about two weeks then one day the gears burned up again. It did the same exact thing. So i took it back and they fixed it again. He didnt know what had caused it to do this again. No cost becuase of the warranty. Well here i am now and i think its going to start doing the same thing again. At 60mph im noticing the rpm's jumping but my speed is the same until it finally changes gears. I have noticed a slight burning smell when i turn the car off. The mechanic told me that it was ok if i seen a small amount of tranny fluid on the ground because it might have to much in it. So im not sure if he's not doing something right or its another problem. Has anyone ever had a problem like this before? And could anyone help me out?

 

Sounds like the torque converter is coming apart. Trash from there will wreck everything in the case !

 

Thanks man. Im going up there tomorrow. I'll be sure to tell him about it.

Also will low transmission fluid casue this. Or how about too much? The mechanic said there isnt a way to check how much fluid is in it. Is this true?

 

The fluid level is check by the venerable "dip stick." The level in the converter is constant by vertue of a pump.

Not enough fluid is bad. This causes over-heating but you should experience some slippage....especially first thing on a cold morning.

Too much fluid is bad, but once hot the tranny will just puke it out via the vent tube.

Sounds like you have a serious problem.......make them fix it right this time !

 

Uh..don't know about a '99, but my '98 A4 has fill/level plug...

 

as far as I know C5's have NO dip stick. you add fluid till the level come up to the fill hole.

 

There are specific procedures for checking/changing AT fluid.

....ooooops, forgive me, I am a MN6 guy ...........

 

ITS NOT OK TO SEE TRANS FLUID ON THE GROUND! If I were you I would find someone else to look at your trans and let the first guy that TRIED to fix it pay for it...................Paul

 

Call Rodney at RPM Transmissions.

 

 

Well it's back in the shop now. After I get it back, Im planning on taking it somewhere else for them to look at. Thanks to everyone for the help I'll post the results when i get her back

 

Run away from this Tranny Mechanic as soon as possible.
No there should be no drips anywhere and is is checked by letting it run and checking the level in the fill hole. Should be full when level with the bottom of the hole. Sounds like you found the only "dipstick" having to do with a C5 auto and that's this mechanic.
Also sounds like your TC. Good MOD time.
Good luck take it to someone that is proficient
