Interested to know if anyone has experience with the Griner manual valve body in a Turbo 400 . This is a spragless setup. I have had a nightmare with the one I purchased from Lonnie Diers at Extreme Automatics. The trans blew up when first installed because of bad thrust installation. Since then it has fried the intermediate clutch pack twice. Can not run normal fluid level as it foams the fluid. Have to run at least 3/4 inch below normal (cold and Hot) levels. Also a nightmare getting anything out of Extreme Automatice in the way of warranty. Have been waiting a year now for him to send replacement parts not to mention about 100 emails. The other issue being he invoiced and said he'd build with an Alloy forward drum but installed a standard steel one. Rip off, Bad Service in the extreme!
