| When i got to work on tuesday morning, went to park car in space, put in reverse, clunk, no reverse, can't get out of first gear. i had to have my car towed 30 miles each way to my mechanic. turns out the planetary gear went, need a new transmission, costing over $3000.00. after doing some research on the internet i see there are thousands of complaints on something called the sunshell gear 4160e that seems to have been a problem on many of gmc passenger cars and light duty trucks. i even came across a service bulletin they put out about the problem, but never any recall on such a problem. i have a 2001 gmc jimmy. the service bulletin runs in autos from 1993-2005. now, i wonder, why no recall on such a huge problem. i mean it's the most costly thing to repair and happens without any warning at all. i would suggest this be looked into, i mean now i get a new transmission from gmc which i'm sure the problem is solved, but how many people have shelled out big bucks to fix this problem and mostly at less than 100,000 miles on their vehicles. tranny's should last longer than that. i am sure i'm not the only complaint received on this subject from what i saw in my research. if it's a defect, recall it and fix it. we, as consumers work hard to have a vehicle we can rely on and to have a major problem like this happen is really not right. obviously gmc is aware there was a problem for some time now. thank you for your attention to this matter. *tr | |||

| Several problems with 2001 gmc jimmy. battery - was leaking & running down engine compartment - (under warranty) dealer was going to replace battery & fix where acid had eat up pan, under coating,wires, etc. dealer did not do any of this - all they did was super glue bad battery connector back to battery. i went back to dealer to complain & was told that they did not have time to even look to verify that nothing was done. warranty expired 2 days later. go figure! brakes - have gone thru 2 sets of pads all around - had to replace 2 rotors so far- as they were eat up completely - nothing left on one side. makes constant grinding noise like brakes are being ridden. lights - had to have emergency switch replaced under warranty.( had no brake lights) transmission - always revving up or dropping down. front end - popping cracking noises. interior lights - dim & light always on everything. ask 1st dealer for a print out of service on vehicle- was told that nothing had been done to it ever. ask 2nd dealer for print out - found that vehicle had been towed in 3 times for problems ( i bought it with 10,000 miles on it) they had replaced a few things several times (forgive me i do not have that info handy at present) also, sometimes ie feels like accelerator sticks. i usually drive chevy - this was my 1st & last gmc (i know that they are the same basically) i feel unsafe in my car & i'm currently trying to get my old chevy running again so i can get rid of this piece of junk!!!! please help if possible. the time line is from july 2002 thru current jan 2 2005. *jb | |||
