Well it had to happen. I needed to replace the transmission in the LSS at 375,000 miles. I noticed that after the car was driven for 20-30 minutes the transmission would downshift out of overdrive when going uphill, and then not shift back onto OD unless I stopped and turned off the ignition and restarted it again. When the shop took a look inside they showed me that all the internal components were well worn. They ordered a replacement, which needed to be built up first, then installed it with ease. The Olds is once again on the streets and everything works perfectly as good as new! Special thanks to Todd Ruggles and the techs at Arrow Transmission for their fine work!
