Servo -Band got burnt for the 3rd time now

no year car told at all wow. 2004 to 2009
2008 last one made USA.
scan the PCM for tranny errors for sure reverse. solenoids and reverse gear is band actviated.
there are 3 gears (at least) called SELECTIONS
PRNDL (or PRND12)
does L work ,car move in loW?
does D work shift up 1,2,3,4? OR SLIPS OR FLARES
OR?
and R fails. well most times that is a bad tranny.
IF ONLY FAILS SAY SO.
IF CAR FAILS IN ALL GEARS MAKE SURE PARK IS NOT STUCK.
the actual box series name is
4-speed 4T65-E automatic


test 1 is make sure shift linkage really does R detent
in the box. AND PARK WORKS AND CAR ROLLS OK IN NEUTRAL.


the shifter goes to R
and reverse lamps glow. AT REAR OF CAR GLOWS.
if yes the reverse band is failing.

As advised by your mechanic, my advise is no different, in the gearbox there are what we term as teeth of different gears and synchronizers...being in such behaviour, your car needs a gearbox overhaul or replacement depending on which will cost you less

solenoids can be replaced with out affecting the transmission
however the burnt oil indicates that the transmission may need a band/ clutch pack adjustment
shifting problems are servo/ solenoids , TR sensor , VSS sensor or the TCM

you have a broken overdrive drum inside the transmission, the only way to repair it is to overhaul or replace the transmission....sorry

I'm assuming you have an automatic trans. So the first thing is check the transmission fluid. To do this have car warmed up, idling, and sitting level. Pull out the transmission dipstick and check level, add if necessary. Also check and see if the fluid has a burnt smell. If the fluid was low and you added fluid road test and if it still slips, and/or the fluid had a burnt smell the transmission needs to be serviced or overhauled. To have major transmission work done go to a good transmission shop, unless you have a lot of mechanical know how and experience I don't reccommend trying this one on your own. Hope this helps. Good Luck.

hi i have a 99 volvo s80 2.0t drives very well but when i select R it doesnt move but the revs go up can any one tell me whats wrong and how much it will cost thanks

possible items are clutch and band adjustments , oil pump pressures and dirty transmission oil
have it diagnosed by an accredited specialist transmission shop

Make sure that you have the transmission software updated. Volvo has had many upgrades on their transmission's control software to address these exact symptoms.
