To change fluid or not....

[696]

Talking to a guy at work who said he believes that by changing trans fluid to often you can make a tranny slip? Anyone heard of this?? I know most new cars say every 35,000 to 50,000 but I've seen on GNType that it's suggested every "spring" tune up. If you have a car with a "perfect" tranny that shifted perfect, smooth, ect,ect and you wanted it to stay that way could changing the fluid and filter to often screw it up?

People all have different rituals on changing fluids. I change mine every summer no matter what on all my cars. Only HAD to rebuild on trans because the lockup solenoid failed and it fried the torque converter on a trip from Albuquerque to Las Cruces. Otherwise my trans last a long time. Fluid never has a chance to varnish and is "always fresh" in the cars. I know people who also only change the fluid after the trans is damaged.

thats a pretty silly belief-------if that were true wouldn't new cars have problems with slipping trannys until the fluid got "old"--------sometimes such beliefs have root in some sort of fact------like when someone does a fluid change and doesnt get the filter installed quite right-----or they use cheap parts that leak or they allow contamination to enter the trans when the pan is removed or using a dirty funnel to put the oil in and something ends up in the valve body??????-------could be the reason for a slipping trans after a fluid change but its sure not due to the new fluid.............RC

Only other thing I could figure is my 07 HHR (granted it's newer car) has no trans fill tube. No way to add tranny fluid, just oil.

Most new cars have "sealed" trannys. The fluid is good for 100,000 miles under normal driving conditions, they say. You can add fluid to them(or change it), there is a plug where the dipstick tube would normally be.

to the OP Change the fluid
