asked by on

i just bought a 1999 chevy z71 for next to nothing from a young man who bought it from a friend. the transmission had gone out and he just bought another vehicle and sold this one to the young man who had a wrecked truck with the same 4l60e transmission his fathere who is a fairly decent mechanic but not very experienced with transmission attempted to install the transmission from the wrecked truck that had 90k miles on it he did not replace the torque converter and once he had transmission installed he says that he cant get it to work he says he has been under the truck while cranked and when he manually shifts the linkage into drive you can feel the truck go into gear and rpms change but he cant get any action at the driveshaft. what could this be? is it worth trying to pay a shop tohunt the problem or just have it rebuilt completely i have a friend who said he can get it done for 1500 at the shop he works at what are your suggestions or possible thoughts on the issue.it cameoutof04
My car has an automatic transmission.

Hi there. The 4l60e transmission could have two things wrong with it. Either the park arm is not disengaging inside the transmission making the transmission load up but not rotate the drive shaft or the transmission is low on oil. Check the oil on the transmission dip stick and see what the level is. The level must be checked with the engine running. If the oil level is at the full mark, then it is possible that the torque converter may have damaged the pump.

Remove a cooler line and put it into a bucket, and for a brief moment start up the engine and shut it off. If oil sprays out of the cooler line, then the pump is producing pressure. However, if no oil comes out of the cool line, then the pump is not working.

If you need further assistance troubleshooting your transmission, then I recommend having the transmission problem diagnosed by a local expert, such as one from YourMechanic. You will be be able to make a better decision about the car after finding out exactly what’s wrong with it.
