Question about 2001 Hyundai Elantra

Tranny slips and window problem... electrical problem..related??

I have a 2001 hyundai elantra with 86,000 miles on it. its an automatic. in january 09 the transmission was flushed. and the fluid is full. recently the transmission started to slip on ocassion. it seems to get stuck in 1st gear and when it finally kicks in it does so "hard". this in turn kicks on the check engine light. the next time i start the car the light is off. now today i noticed that sometimes i can still use the power windows after the car is turned off and the keys are out of the ignition. hmmm, could this be an electrical problem that would tie in to the transmission? could it be one thing that is causing both problems? is there something i could do or check myself before i have to take it in? any help would be appreciated... thank you

Was the fluid brownish and burnt smelling when you checked it before the change to new fluid? If so you may have left the fluid in too long causing damage. Hyundai recommend you change the fluid every 30,000 miles using a fluid called SP-3. Anything else can ruin it and many shops don't use it because it's fairly expensive but it must be used regardless. The filter is in the transmission and not meant to be changed so you may want to double check what fluid was put in. if the right fluid was used; new fluid will actually bring out the problems in a transmission quicker then leaving old fluid in so you may have had a problem beforehand or left the old stuff in too long.
A rebuild,replacement or tourqe converter change may be in order.

Your windows are fine. The ability to rise and lower them were an option Hyundai included for the Elantra. In fact, if you leave your lights on when you exit the car they will shut off automatically when you close the door.

I think the first place you should start is by changing the fuel filter. If your fuel filter is partly plugged, it can make you think it's the transmission, when, in fact, it's actually the engine starving for fuel. It could also be your speed sensor, if the fuel filter doesn't make a difference. Good luck!

I have hyndai elantra 2001 automatic sometimes hesitant to start.

Sounds like a fuel pressure problem. Check/inspect your electrical connections to the fuel pump (power & ground). Also, connect a fuel pressure gauge to the fuel line at the fuel injector rail - leave it connected so if and when you have this problem again, you will be able to determine if the cause is fuel pressure/pump.

Power steering pump--2001 hyundai elantra

If it's not a serpetine belt, max deflection of 3/4" on longest segment should be safe,  don't make alternator belt tight as a drum or you will burn out alternator bearings quickly.  If it has serpentine belt, the spring tensioner should keep the belt properly tensioned unless it's worn out.
It only needs to be tight enough to not slip, too loose will squeal and you will have to tighten,  to tight will kill alternator and you will spend $$.
