First, make sure the fluid is up, but you probably did that already. Second, check to see if the fluid smells burnt. If it does you've been having clutch slipping problems and it's probably near gone anyway. If you're trying to squeeze a little more life out of an older vehicle there are a few things you can do. What you're describing seems like a "valve body" issue, where seals are possibly leaking pressure and valves are not moving properly. When they warm up they might work better... sometimes... if the stars are aligned and you hold your breath. First, let it warm up before putting it in gear. That might help prevent transmission slipping but maybe not. Second, there are some transmission seal additives that can soften the seals of a transmission valve body and help it last a little longer. Sometimes using these products make the seals SO soft that they give out, but it's all a gamble anyway so if the transmission is getting to be marginal, go for it. One brand is called "Trans-X" and it seems to be a little better than some of the others, at least by my experience. Obviously a transmission rebuild would be better but in the real world some of us can't afford that and we need out vehicles to keep running.
If the transmission is healthy and any/all adjustments are done properly there should be no slippage.
Check the automatic transmission fluid level. If it is low add enough to reach the full mark. If it is not low seek professional help. If you have to add fluid use only Genuine Honda automatic transmission fluid. Use no substitute.
A 1994 Mazda Miata's automatic transmission may slip in 4th gear if the bands are heavily worn. When the bands become worn, they are unable to grip properly and cause slippage.
Do you have enough transmission fluid in the trans? Be sure it is full and you will notice and instant change. If not, have a transmission mechanic check the bands to ensure there is no slippage, otherwise, I'm not sure. I hope this helps, E200
check your transmission fluid, if it is low it will slip
Automatic transmission shifts can be related to fluid temperature and some vehicles also have sport style settings that can change shift quality. If the shifting is irregular and causing unusually high engine speeds this could be a symptom of transmission gear slippage. Gear slippage can result in transmission damage, and should be checked as soon as possible. Automatic transmissions are complex systems, and their overhaul/replacement can be very expensive repairs.
Transmission component slippage.
Low or dirty transmission fluid Transmission bands are worn
Belt slippage usually results in a squeeling noise and the belt will eventually heat up and self-destruct. You may have a clutch problem if the power is not getting from the engine to the tranny. Or it can be a trans problem is something inside is worn and slipping. Check the transmission fluid if it is an automatic. If the transmission fluid is good and it is an automatic, you will probebly have to take it to a transmission shop. Very little can be done to repair an automatic without removing it from the vehicle. If it is a manual, have a qualified mechanic check the clutch. I've had the same problem,it turned out to be transmission problem. I had to pay $1400 to rebuild my transmission. The longer you drive with a bad transmission,the more damage is being done to it.
my car has been slipping in the transmission would it be the that the transmission is bad or is the filiter and the transmission fluid needing changed?
You should have no issues should you use a Sythetic transmission fluid such as Nulon Multi vehicle fluid do not use regular grade auto fluid this can cause power steering pump slippage and or failure
Running slow with high rpm is a sign of slippage. If the vehicle is a straight drive then the clutch is not grabbing and is slipping, if its an automatic then the transmission is slipping internally.
