I have a 2000 chevy s10 pickup and i having starting problems. i have to put the gear shift to neutral and back into park and then it will start. can someone tell me what i need to fix?

Sounds like your transfer case in neutral. You have to engage the transfer case back into gear then shift selector to drive or reverse. When your transfer is in neutral the transmission will not operate. Good luck.

good chance the gear selector has slipped on the lever and requires repositioning and tightening

Two possible causes could be a bad neutral safety switch (enables the vehicle to start in only Park or Neutral) or the transmission linkage may need adjusting. If you feel significant "play" in the gear shift (from what you described, it appears to have a lot of play) the linkage will need to be adjusted to get the gear shift to "lock in" to the individual gears instead of sliding.

Sounds like the shift cable needs to be adjusted, it may not be going completely into park at the Transmission.

Its sounds like the shift lever is loose at the trans, kick down lever at the same place might be your other issues. Left side of trans just above the pan is the location

Check your master and slave, If your slave is not fully depressing the pressure plate it would be very hard to shift.

Low fluid would not cause this. However there is a bolt on the side of the trans that you remove and put your finger in to check the level. If you put your pinky in and no fluid comes out it is low.

The slave often goes on the chevy's. It is internal, you have to pull the trans to replace it.

Also a pressure plate that is collapsing can cause the same problem. You are pushing all the way down, but it is not releasing.
Hope this helps.

theres a shift cable if its floor model,linkage for column model.

also a s10 owner, my truck shuts off when i put it in park...yours is your shift cable ..adjust cable (without running) p,r,n,d and so on, making sure your indicator is in correct spot.

Has anyone tried lubricating & or adjusting linkages/cable?

neutral safety switch..:) good luck
