signs of an overfilled transmission

So, if anyone has read my previous post, after I replaced the fluid the tranny started to slip. Well, this morning I checked the fluid and it was full to the hot mark. Would an overfilled transmission slip? My car acts different on different days. Today, its pissed off, i love it, but on some days, it slips like crazy, in all gears.

So, what do you guys think?

Hell yes the transmission is going to rumble and slip if it is overfilled. I strongly recommend that you siphon the transmission fluid out and re-fill it to the correct level with TRANS-X fluid additive or equivalent. The fluid level is going to be slightly higher on the dipstick when the engine is warm and slightly lower when the engine is sitting cold. This is because the fluid and the transmission itself expands when it is hot. YOU HAVE TO COMPENSATE FOR HEAT RELATED EXPANSION. Fill to the hot level on the dipstick when the transmission is hot and add fluid little by little always wiping off the dipstick to get an accurate reading.

I don't believe in the Trans-X crap, I wouldn't put it in my trans. Change your fluid regularly and make sure it's nice and red and you shouldn't need that crap.

I agree that you should always do transmission flushing whenever the fluid starts to smell burnt, but if you're siphoning maybe 20 fluid ounces the additive is the better choice just due to the lowered cost and ability for universal use.

Those additives do a good job at sealing leaks, and reducing oil flow Not something I'd use.. A quart of tranny fluid is $5..

If the fluid starts to smell burnt than you've already shortened the life of your transmission components significantly. If you read any mechanics manual they recommend to change the fluid every 30,000 miles. When you replace the fluid the old fluid should still look red. It shouldn't look dark like motor oil.

The additive is a placebo, IMO, I used it once and it didn't do anything except make my job more difficult than it should have been when I had to remove my valve body. The thing was covered in that gunk and it was a PITA to clean up. I talked to a friend who owns a transmission shop and he agreed that he hates when customers use it and then he has to work on it. He also says that if you resort to using that stuff you didn't maintain the transmission correctly and probably need a rebuild anyway, so you might as well save your $10 for that. Yet many people recommend using it, I just don't get it.
