Only 2nd gear no 1st and rev - Peg Perego John Deere Turf Tractor

sounds like worn piston rings. In 1st ans 2nd gears the engine wants to rev highest to make maximum powere so rings get a bit worn and oil will be sucked past. Change the rings and try again

It winds up in 1st and then shifts right from 1st into 3rd. Then never shifts into 4th. Plus rev is gone. You broke the sun shell. The transmission will need to rebuilt or replaced.

The splines in the bucket are stripped out this is very common at my shop it needs an overhaul.

the gear changing selectors are faulty and needing inspecting for damage ,gear box removal job

that's a bad neutral safety switch...it's a shop repair...now, the reason it goes bad:

the 1st gear is for getting the bike moving, period...you "never" wind out in 1st gear...ever...high rpm and going from 1st to 2nd is very bad for a transmission...think about how much movement is happening to go from the bottom, past neutral, to 2nd gear...that's where most trans damage occurs...once you start moving, go to 2nd, then rev it out... remember...1st gear is for getting moving only...

No forward movement in OD or D, but L2, L1 and R work: Forward sprag is broken. R&R. Try not to run or drive the car or further damage could result.

Do you have manual 1st? If so, can you shift through the gears...i.e. manual 1st to manual 2nd then 'D' then 'OD'??? Only 1st and 2nd gears use the forward sprag unless the LO/Rev clutch is engaged...i.e. 1st and 2nd if in "drive". If you can shift threw the gears manually then, yes, your forward sprag broke.

If no manual 1st then your sprag is not what broke. Sounds like you blew up the rear planet. If you pull the pan and find chunks of iron and steel, then that is probably what happened. If you have reverse then it is not the pump. If the pump was bad you would have no line pressure and it would slip in rev. or no rev. Not the beef sun shell either because you have rev., a broken sun shell would cause no 2nd, 4th and rev. gears. Either way the trans needs to come out and torn down and it will be easily found what went. Good luck and thank you for using Fixya.

\'93 Hyundai Lantra, automatic transmission has trouble changing up from 1st to 2nd, it tends to rev on a bit, clunks once or twice before changing to 2nd, other gears seem to be ok. Oil levels are ok and have recently replaced the transmission oil (yes the correct oil was used)

drain and fill trans with fresh fluid
trans may have to be rebuilt

sorry

you are experiencing early to mid stage transmission failure.

The Catera is designed to heat the automatic transmission fluid when cold by extending the time the car stays in first gear. This is by design and not a defect.
