SOURCE: 99 gmc jimmy transmission slipping

hi check the colour of your transmission fliud is it should a medium red if it looks dirty brown or any other colour that would suggust your clutchs are slipping if your transmission fluid is low or over filled it will cause your problem you can drain your fluid remove your lower sump pan clean the boxes main body and filter replace the oil and try there is no gaurentee it will work but this is a basic you can do and these type of repair can resolve your problem if the fliud is brown then this and an adjustment of of the boxes clutchs and bands must be done this can be done with the transmission in sitution there are other things that can cause the problem but these are well worth doing first as it will not cost a fortune and has a good chance of success yates210456

SOURCE: transmission - no reverse

i had to put a new trans in my 2000 jimmy about a year ago there is something inside called a "reverse hub" its made from aluminum and not very hard to break..when mine broke i was stuck trying to move in reverse and it heard a pop then a winding down noise and sure enough its the reverse hub to fix it i just had the trans rebuilt

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.
