I am hoping someone has some experience with this I just bought a 1990 K5 and there is a noise(bang) coming from my drivetrain. shifting back and forth reverse to drive and when it shifts into the next gear. I have the local tranny shop and drive line shop stumpedits not tin the axles or drivelines I checked the keeper clip in the T-case and I also looked at the flex plate it seems to be fine.
has anyone came across this problem?
700r4/np241
and does anyone know if there is a legth difference between the 241 and the 208?:confused:

remove the driveshaft....put some general purpose grease inside the slip yoke....reinstall the driveshaft....

mine did it for a year before i figured it out. Gm sells some fancy grease for it if you have to spend money.

CHECK THE U JOINTS!!! The pins inside the u joints could be bad or non-existent and when there is pressure put on the driveshaft it causes it to *ting* when it settles into place. The last time i did my U joints i forgot to grease them. About 3-4,000 miles later this exact same problem happened to me. I got scared needless to say, but as soon as i replaced the joints, it stopped doing it. I would also try greasing the slip yoke as he said. I hope this helps.

sounds weird but I will try the grease. as far as U joints they r all brand new. front to back. axles also any other ideas please speak up i will try just about anything I am getting tired of it quick thanks for the input:D

didnt work I am thinkin it might be the torque converter if I wasnt bald I would be pullin hair

It does this in 2 and 4wd? What about when the tc is in nutral? I dont quite see how it could be your torque converter.
