[Shop-talk] Lucas Transmission Fix

Wed Feb 21 06:30:14 MST 2024

Hi Moose,

Yes, when someone does not want to take your money for doing the work they
normally would do, that says something.

If it is just a seal, though, Dodge almost certainly bought the seals from
some company that makes them. Perhaps you could find the specs for the seal
and look-up industrial supply companies and try to match it? We do this for
bearings and seals for the old British stuff.

Again, though, if the repair garages do not want to work on it, there
probably is some sound reason(s).

I have an engine rear main seal leak on my '03 GMC Savana and used a seal
leak additive which did stop the leak for a while, but it has returned.

I am not 100% positive that it was the source of the problem, but after
adding the stop-leak to the engine oil, I noticed that my oil pressure
started to drop noticeably and I eventually started hearing lifter noise. I
changed the oil filter (it was a Champion filter) and the pressure
immediately went back to normal. I swore I would never use another Champion
filter as they apparently do not have an effective bypass valve in them.I
thought the problem was filter-related.

After a few months of local driving (a few hundred miles) I noticed the oil
pressure was dropping again, I again replaced the filter and the oil
pressure went back to normal.

I cannot prove it, but I believe the stop leak was plugging the filter as
well as plugging the leak. It made me very cautious about using anything
like this again.

best,

doug
