Well the transmission finally bit the dust. Originally the radiator cracked and leaked water into the transmission lines. I did a few repairs and have done a lot of driving since. I’ve gone on seven long road trips and towed two cars, three hours each. I’ve also done a lot of towing around town. I drove 2 hours to go see my parents this past weekend and stopped at a red light. When the light turned green I started to move until the engine rev’d high and then slammed into second hard. I stopped at another red light and the Caddy wouldn’t move at all except for reverse. Maybe I can repair it, but so far is sounds like my 1st gear clutch pack is probably toast. I did notice a whining noise coming from the transmission a week before, but it went away. Also over the last month I’ve felt like I was losing power from a dead stop, so it was probably slipping.
I’m now trying to decide if I want to swap in a 4L80e, a 6L80e, or a manual.
