A few thoughs, I had my trans rebuilt on a 75 Coupe DeVille back in 1989, cost me $1200. $1400 today sounds like a good deal. Do it!
Get rid of that POS GM alternator & get one from Quality Power, it's a high output rebuilt Denso.
Keeping a North East 4runner on the road is hard work after all these years. My 3RZ will never see a salty road again! My baby's had enough.
If this 3rd alternator goes to shit I’ll try and get my money back. And get a denso one. Denso makes a alternator for the Cadillac. But it’s crazy because plenty of people run autozone alternator without issue. It’s just my luck.
