My '87 B-II hs 2.9 with auto trans/OD. When hot and usually after driving 60+ Mph the trans leaks *bad*! Like a faucet, it pours out from the bell housing. It took 5 quarts just o get it home 2 blocks. Any help? How much to overhaul a 4ald trans? Really want to keep it, but also has a prob where it gets hot under strss, when using A/C. Thans in advance for any help!
