I took my truck to get my oil changed and my transmission fluids changed as well, it took about 3 hours. They finally called me to go over everything, and let me know my truck was finished and ready to be picked up. When I arrived to pick my truck up, everyone there was very nice, i spent almost $400 getting my oil changed, my transmission fluids changed, a coolant flush, and to replace my gas filter. Therefore i spent a big amount of money and expected to be happy with the outcome. However, that was not the case. when I picked my truck up, it started and everything was fine. I drove to royal farms and went to put my truck in park, and it would not go into park. It wouldn't even tell me what gear i was in. I tried turning my truck off and back on, but it wouldn't start, because i couldn't see what gear i was in. i called hertrich's freaking out. my truck is an 02 GMC Sierra, with only 90,000 miles on it in perfect condition, it's never ran into any major issues what so ever. I take my truck back for them to look at, they were all very apologetic, and were quite well with my temper. The guy, im guessing was the manager came and explained what they had broke. they broke the "plastic" piece that is on my transmission cable and that explained why it wouldn't go into park correctly. I went to a different place to get my oil changed, and when they were done they went over everything about my truck, and told me that whoever last worked on my truck, did not put an oil filter back in my truck causing it to leak.Hertrich's handled the situation very well, offering me a rental and kept my truck over night to fix it, but sadly due to this experience they will never see my truck again.
