auto transmission slipping in upper gears
trying to find out steps to do auto trani fluid flush for this car see if I can prolong it's life can't locate manual
I do not think that a tranny flush will resolve your issues or even prolong the inevitable (to have your tranny rebuild) A filter change and fluid change may helpa bit but again :( Here are some other possibilities. There are many causes of automatic transmission slipping as the system itself is quite complex in its make up. Here are some of the prime automatic transmission slipping causes.
Torque Converter Malfunction
Modern automatic transmission systems are hydraulic in nature and the power for driving the transmission comes through the torque converter. It is the torque converter which pressurizes the transmission fluid and provides hydraulic power to shift gears. A malfunctioning torque converter, with a reduced pressurizing capacity can be one of the main causes of automatic transmission slipping.
Transmission Band Problems
For the proper working of an automatic transmission unit, it is vital that the transmission bands are adjusted well. If they are not, gears can slip out of place and cause the transmission to slip.
Worn Out Gears of Transmission
Gears which have worn out along with warn out transmission bands can be the prime causes of a slipping transmission. Warn out gears do not engage properly causing the transmission to slip.
Drop in Level of Transmission Fluid
One of the common reasons of slipping in automatic transmission is inadequate levels of transmission fluid which adversely affects gear functioning and its shifting leading to slipping.
To change the fluid in an automatic transmission you usually need a transmission fluid exchange machine. Unfortunately, these are rather expensive for the average person, so I recommend going to a mechanic for an automatic transmission flush. My understanding is that transmission flushes should be done around every 60,000 miles or every 5 years. However, new cars with synthetic fluid may be recommending every 100,000 miles or 10 years
Manual transmissions are another story and it is usually very easy to change the fluid in them yourself.
Brandon is right, also check to see if your throttle position sensor has a flat spot, but to do this you need to go hook it up to a lab scope and see if you have any glitches or drop outs, this can cause shifting problems and is commonly overlooked
Step one of transmission diagnosis is fluid level and condition. See your owners manual for how to check it.
There's a maint interval listed in the same manual, hopefully youve been following it. If not, bring it up date.
Changing the fluid with the correct fluid listed in the manual usually never hurts unless your tranny is totally worn out (and near death anyway).
If general, I prefer to drop the pan and change the pan gasket (and maybe the filter depending on the vehicle). Dropping the pan allows you totally wipe the dirt out of it, and they fluid usually comes out a lot cleaner than it does with a flush.
I suggest asking oldturkey03 where the "band adjustment" is on your accord tranny (sarcasm). That guy has no business giving advice. He just googled some crap. Check elsewhere on the net, iatn.net or honda and accord forums for more accurate info (or ask a real honda expert). These 98-2005 accord V6 are known for tranny probs.
Oldturkey should also tell you how many torque converters that he's seen go bad, because in all my years as a mechanic i've never had to replace one.
