Transmission shifts hard but not all the time. hard like ka-thud hard. and sometimes in a higher gear than needed. could this be an electrical problem? tks

find a tranny man,
any ASE shop works
ask em.' to CHeck it out.

No idea without a drive so please ask a local mechanic to have a look for you

orbital clutches slipping , needs stripping

I suggest you have a transmission shop take a close look at your vehicle. That year accord with a v6 and automatic transmission had a recall for the transmission and your problem seems to be a slowly dying tranny.

buy shudder fix might need to get it from a transmission shop its the torque converter lockup causeing the shudder

It sounds like a tork conveter lockup switch, have the transmisson serviced oil and filter changed then and add Lucas transmisson treatment to help smooth out hte shifting pattern and stop the problem if there was drag on the clutches it may have stalled out.

check and replace filter and fluids just like oil it tends to burn up and blacking and needs to be changed and flushed checking your tranny fluid it should be a red color not a dark red or with a black tint

sounds like a shift solenoid in the trans.

I had a similar problem with my 1997 F250 only with 1st & 2nd gear. At the same time the ABS light was on and the speedometer was acting eratic. In my case it was a bad speed sensor on the rear differential. About $30.00 and took me less than 15 minutes to fix.

I'm assuming you have already looked at the trans for any loose or worn electrical or vacuum lines and connections.

hi you need the seals replacing in the box when they are cold the become hard as they warm up they start to do what there are suppose to yates210456
