    I have a 1988 c1500 with an hm290 tranny and i cant engage 1st 5th or rverse.
    The shifter is really really wobbly and i thought that was the problem. But after driving for severl weeks
    I have discovered its Probablr got something to do with the detent springs and plungers. So i rodered them and i cannot
    Find absolutely any info on how to replace them. I cant even find info on how to rebuild them.
    All i find are people talking about how techs wont even touch the transmissions etc.
    I need to find out how to do this and if i can fix the shifter wonble without tearing the trans apart then that would be nicE.
