86' silverado, automatic. On occasion have issues shifting from park to drive. Check fluid and changed filter. I believe a probable shifting cable adjustment. Transmission runs and shifts smooth ot

i take it is a automatic check gearbox transmission fluid or the torque converter may be at fault

Is this an automatic? I can't tell if column shift or console? With column shift, Did you try taking shift linkage loose from tranny and shifting by hand? There are safety issues with trying that, make sure functional parking brake is set and the wheels are blocked. Also, have a helper sitting there with foot on the brake. Safety is your responsibility.

Maybe just a tranny issue, I'm not a tranny person.


You might be able to start it and kill it in drive? There are safety issues trying this and I don't want the responsibility. Safety is you responsibility.

It can be issue with gears or problem with transmission and needs to be rebuilt. Also get the ****** fluid checked. If it's low, then such problems occurs.

Thanks.

i would change the ****** filter see if that fixes the problem!

if u cant select a gear such as go in reverse or into drive when moving selector from park than place into park and look under vehicle attached to the transmission on the drivers side is the selector cable on a lot of 99s this gets rusty and pops off or breaks if popped off spray with a lube to free up the clip and pop back on may have to replace it if to damaged --if cable is fine than problem will be an internal and usually pops a check engine code --check fluid level and smell if smells burnt and looks brownish than fluid bad[filter possible clogged or band-clutch pack bad] needs to be changed as well as filter may get lucky that wont cause internal damage but usually the cable is ur problem good luck

No not your U-joints. They usually make noise when you shift in to gear or put on the gas in gear or let off the gas in gear when dirving. They would make a clunking noise.
Have you checked the Transmission fluid level? A low fluid level may cause hesitations. The fluid should be a nice bright redish color. If it is brownish and yucky looking it is time to change the filter and fluid.
Remember that the level marks on the dip stick are measured in pints and not quarts like the oil is. You need to put the emergency brake on and stick it in neutral and start the engine to check auotmotic transmissions. If it is low then fill it to the full mark. If any fluid at all shows on the stick then unless it is burnt and brown it is probably not your problem. If none showed on the stick you might get lucky. Keep me informed and I could use a thumbs up for me time please. The Raz Shack!!!

check over all enigne mounts
check select cable /linkages
adjust the safety switch

check transmission fluid .if low add to the right amount. if looks dark brown smells burnt.change fluid and filter.

Replace the vehicle speed sensor, it's located in the tailhousing of the transfercase

How to prevent the transmission from damage
(The filter usually is screen type and can be cleaned when remove bottom cover. but this is not to be done at regular maintenance inspection.)
- Regularly check your parking space for leaks. Doesn't matter, is it the engine oil leak, power steering fluid or transmission fluid; if you discover any, get it fixed before it caused something serious.
- Once in a while check the transmission fluid level and condition. Not all cars however have the automatic transmission dipstick, in some cars, for example, in late Volkswagen models, the transmission fluid can only be checked by the dealer. Consult with your owner's manual for details. If the transmission fluid level is too low, there is a leak somewhere that needs to be fixed.
- Change the fluid as often as it said in your owner's manual or when it becomes too dark (rather brown than red) or dirty.
Also, keep in mind that an automatic transmission can not be drained completely - there is always some transmission fluid left inside the transmission (the torque converter, in the valve body, etc.) which means you only can change about %60 of the fluid at once. This is one more reason to change it more often.

- Use only the same type of the transmission fluid as specified in the owner's manual or on the dipstick. Some vehicles (e.g Dodge Caravan) are very sensitive to fluid type
- Never shift to the Reverse or Parking until the car comes to a complete stop.
- Never shift from the Parking mode when engine rpm is higher than normal idle.
- Always hold a brakes down when shifting from Parking.
- The automatic transmission can be damaged if towing with the drive wheels on the road. Always use a dolly or place powered wheels on the towing platform (if the vehicle is front wheel drive - tow it from the front leaving rear wheels on the road.
