What about oil consumption? Ha, not sure what I hate most, road salt or leaks, either messes up my garage floor, but at least with leaks, can do something about this.
Talking to a complete idiot here, putting up with GM rope seals for some odd 30 years, have that Chinese finger puller tool for replacing the upper rope, but gave up, only good for about 5,000 miles and would leak again. Could only fill to the add mark or would end up with a quart of oil on the garage floor. One cure to get rid of this in the 80's was to switch to Japanese made cars, felt unpatriotic by doing this, but also had enough. No more GM loyalty for awhile.
Ha, was kicking myself in my butt for not replacing the rear seal in my P-30 motorhome, had the AT pulled for a complete overhaul. Was laying under the vehicle for five minutes staring at it, would have been so easy to replace at that time, but looked good, so I left it, a year later, started leaking. Time to kick my own butt.
But I tossed a quart of Lucas Engine oil seal conditioner in the engine oil, that stopped it, least for now. Ha, can always pull the transmission again. Also hail getting old, use to be able to hold that thing up with one hand to start the first bolt. Now I have to use two hands to hold it up, so need somebody else to start that one bolt. But with transaxles, need at least two guys to help me. Not making it any easier with this new stuff.
