Slippy tranny in 2-3rd gear more in 3rd on my honda trx650fa four trax rincon

I would say that one or more of the shifter selectors have been put back in the wrong position on the gearbox. I remember years ago on an old Holden mixing them up. The gears were stuck in neutral and reverse at the same time. You may have to play with the shifters to get them in the correct spot.

pull the starter out, check all the teeth on the starter gear, replace if any are broken

this car warns you of tranny errros, 2 ways.
flashing D selector (some years)
1996 and newer, most...switch to this way.
and with a scan tool shows DTC errors. P07xx (vast numbers)
CHECK ENGINE LIGHT CAN BE ON, RUNNING?
and can show tranny failures. but scanning is best.
some countries mask tranny errors.. not USA. (loc, not stated)
in your car the PCM shifts the tranny , not you.
the PCM can in fact go to limphome for the tranny.
and can skip gears.
if a tranny input sensor is faulting the PCM (OBD2) scan will find this error,
so scan it.
be advised, most Autozoned, stores can NOT scan for the HONDA DTCs custom to HONDA. P1 or P2 codes.
they can do P0xxx codes, mostly and are blind. mostly.
use a real tool to scan it.

Check transmission fluid level. If it's ok need to have trans fluid pressure checked. Need schematic, but should be a port on the side of trans for this. If to in depth then take it to a repair shop. Could just have a clogged trans filter.

i found this. might be the same problem as your atv.

good luck

checked fluid level? sounds slippy so check that.. and check that your shifter is all secure and nothings broken dude... probably low on fluids.

I am having problems with the drive gear it seems like its not going into gear. It drives fine when Im shifting it in 2,3rd and 4th gear. I have had the gearbox function light came on then will reset its self. I was having the check engine light on and skips between 40 and 60? Its a 2000 S type 8v with 61,000 miles! Does anyone know what could be wrong?

time to go to a tranny shop, but contact your local honda dealership first i believe there was a recall on those model trannys

it has a problem with the second gear drum it cracks and does not fully engauge the n shifts to 3rd ..many honda owners also learn the 8 bucks a quart is the only fluid to pour in a honda..but remember 3 qaurts per drain and fill the tranny holds 7q ....it will take a case to do a drain flush...a high pressure flush will ruin a automatic tranny with alot of miles or metal deposits floating around inside..DRAIN AND FILL 3 QUARTS AT A TIME NO GASKET NEEDED ITS BUILT AND DESIGNED LIKE A MANUAL TRANNY

Had the same problem. had the soiniod body changedbeginning of winter. Tranny shift Smoother but problem can back the next spring but less often then before.

Noticed that it was happening on hot day and after driving no more than an hour. Noticed that it was happening also in stop and go traffic.

Sometimes just putting the Tranny at Park and stopping the engine on a RED light fixes the problem.

I haven't gone back to the Tranny Shop.
