I have 2003 Elantra on which I have 104000 miles. So far I have done oil changes at regular intervals, air filter change and routine wear and tear item replacements (Break pads mainly). It hasn't given me any problem what so ever. Now I am thinking of giving it a long due and good service - Changing coolant, transmission fluid, timing belt etc. I plan to do transmission fluid change myself. Can some one guide me through the steps for changing the same or point me to place where I can find one. I went to hmaservice.com but couldn't find it.

Also do I need to replace water pump when I go for timing belt replacement?

Thanks

Since you're working near the pump anyway and the car has over 100k, you might as well change it out. I had my tranny flush done at the dealer, so I can't offer any sage advice about *how* to do it, but one thing for certain, use ONLY ONLY ONLY the fluid recommended in the owners manual- SP III. Any other AT fluides, INCLUDING the ones that claim to be universal, can trash your transmission. As I understand it, there are cleaning agents in other AT fluids that can damage the innards of the Hyundai tranny (the solvents can actually dissolve the torque converter blades because of the material they are made out of). Basically you have to go to a dealer to buy SP III (either Hyundai, Kia or Mitsubishi, as those are the cars that use it). When I got my tranny flush and radiator flush done at the dealer, I got away for less than $200 for both.

Being a DIY kind-of-guy myself, I routinely service the automatic transmissions in my cars. It's not that hard a job to perform, however, I suggest you not do this but follow Doohickie's advice to have the tranny flushed by a dealer or service shop. The DIY procedure basically replaces only 1/2 of the fluid inside the transmission. The other half is trapped inside the torque converter and can only be removed by a machine that pumps or flushes out all the old fluid, displacing it with new fluid. Flushing also removes sludge buildup that is trapped inside nooks and crannies, not just the sump pan. I perform the the DIY procedure on cars that have a tranny service interval of 30 to 35K, but I still have a full flush performed every 100 to 120K. You car is at 100K. It needs the full flush service.
