Harsh shift points, delayed shift points, mushy power. tranny rebuilt at 36900. i am original owner, all highway miles, mature driver. tranny been sluggish ever since Massey Yardley rebuilt it, never was road tested after rebuild.

No reason to replace a PCM behind the glove box

I have the same car, a 2004 V8

I replaced the One & only solenoid pressure control pack on mine

Having owned a trans shop in New Jersey years ago, I find your remarks
rather harsh

If they rebuilt the unit correctly , it should be fine & it should not have failed in 8 years,
if you changed the fluid every 30,000 miles, then what happened & why?

What were you told & why are you not back there?

Were updates done on the trans to correct the original problem
or any mention of a dealer flashing updates into the pcm?

If tranny is manual shift you may have a bearing and or bad gear. Try changing tranny fluid. Check manual for correct fluid may use tranny fluid rather than gear oil. I recommend using Royal Purple fluid or gear oil. This very expensive but will slicken up the shifting and extend bearing and gear life.

There is a recall on your tranny take it to a Jeep dealer and tell them you waant the tranny recall done ours did the same thing, there is some seal that goes bad.

Also, I quote this comments form other owners with this problem:
Our 2005 grand cherokee had tranny poblems at 30,000 mi. It was a bearing in the trans. They rebuilt it under warranty. the symptoms: when you shift from park to drive and step on the gas there was a delay and it would bang onto gear. They said this was a problem on a lot of Laredos. Now at 50,000 more tranny problems. not shifting right, the engine light is on and it lights up around all of the tranny indicators on the dash PRND will all be lit up. After several trips to the dealer it is the Trans Control module or TCM at a cost of 400.00 and of course not covered in the 70,000 mi warranty.

Them, I suggtes scanned the TCM for any stored codes there.

Good luck.

hate to say it but your tranny is shot..this is a common transmission,check your local junk yard for a good used one..

first check the detent cable from the trans to the accelorator is is out of adjustment. move the adjuster (((( one ))))) click at a time. mark where it is first then go in the same direction if it gets better keep going till it's right if it gets worse then start at the original spot and go the other direction.you won't need to go too many clicks.let me know

2003 lincoln ls harsh reverse...transmission has been rebuilt with new solenoid pack & taken to dealer to reprogram pcm!!!!!!!! wat else is left

Not unless you are going to be towing or hauling a large load. Lots of driving does not mean lots of shifting. Do you do most of it on the highway or dozens of short hops around town? Are you the original owner of this Civic or did someone else put miles on it before you bought it? If it lasted 20 years without wearing out, a heavy duty clutch probably isn't needed.

If you shift a lot with a heavy foot on the gas, a heavier clutch might do you some good but if you are a normal driver who puts lots of miles between up and down shifting, stick with a standard clutch.

I never trust rebuilt trannies unless i rebuild them myslef....Beefing up valve bodies sometime leads to premature wear and tear...the kit could be malfuctioning aswell. Chefck fluids and replace the filter in it, if that doesnt fix it, then take it back to the tech, and demand free service :)
