I don't recommend changing the manual transmission oil unless you are prepared to change several oil seals and gaskets (requires trans. removal and disassembly). Like the clutch cylinder seals, replacing old fluid with new can cause *rapid deterioration of seals & gaskets. Keep in mind that the transmission gear oil is not subjected to the high heat and pressure as crankcase motor oil. In over 17 years of record keeping we have no reports of premature manual transmission parts failures (due to wear) including transmissions with 150k miles plus, Several auto manufacturers (Saab, etc.) say that it is not necessary to change the transmission oil, ever. DeLorean transmission removal is very labor intensive and costly, if you have deep pockets and you feel the need to change the trans oil than do so. If you decide to skip this service procedure and someone asks "have you ever changed your manual transmission oil? ; you can tell them that "DMC Joe said its OK not to". PS: If the manual trans is removed for service you should replace the oil, seals, and gaskets before returning the trans to service. *50% incident rate DMC Joe DeLorean Help dmchelp@xxxx www.dmc.tv http://shopping.oraclesmallbusiness.com/dsvstore ----- Original Message ----- From: "Joe Thome" <joethome@xxxx> To: <dmcnews@xxxxxxxxxxxxxxx> Sent: Tuesday, February 05, 2002 8:42 PM Subject: [DML] Tranny filler plug frozen > Hello fellow list members, > > The filler plug on the 5-speed transmission on my '81 VIN 6467 is frozen tight. I've tried WD 40 and some penetrating oil called Blaster. I also tapped lightly on the plug but it won't budge. Is there any way to re-fill this transmission other than through the filler plug hole? > > Joe Thome > > > > > [Non-text portions of this message have been removed] > > > > To address comments privately to the moderating team, please address: > moderator@xxxx > > To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews > > Your use of Yahoo!
