Ok guys, another problem with this thing. Just replaced a fan clutch yet still sounds loud under the hood. Service guy said i bought a heavy duty fan clutch and it is just opening up more and should sound that way. Could be true. Now I am having a problem with possibly overdrive. The last time i had an isuue with overdrive jumping in and out i replaced the clockspring and all was well. Now i can only tell you this acts like an overdrive problem again but not the same exactly, It does not jump in and out of overdrive but takes too long to shift out of overdrive. RPM's look good for the most part. So question is do i start with the clockspring again or look for something else?

 

not sure about the overdrive, but the fan clutch will make noise for the first few miles after a cold start, and if it is a heavy duty one it will make some noise contantly. As long as it's not making your belt slip it's not hurting anything but your wallet at the pump

 

What engine do you have that will narrow the possibilities. So what you are saying is you put your foot down and it doesn't want to leave overdrive or it just takes a while. When was the last time your transmission fluid and filter were changed?

 

on the clutch fan issue, it WILL be loud on a cold startup every day, more so with a heavy duty unit bc the fluid is settling out, as long as it goes away shortly (give it a mile or so) it is fine.

on the trans issue, sluggish shifting is most commonly low hydraulic pressure (low fluid in the trans)

check the fluid level and top it off (needs to be checked with transmission at operating temperature, engine running, trans in nuetral, parked on a level surface)

the trans is said to be at operating temperature after driving between 12 and 15 miles

 

Also could be a bad transmission output sensor.

Or you need to do a TV cable adjustment.

Also low fluid will cause this as Sharps stated.
