Joel, I think the best thing is agree to disagree. Personally, I go along with what your saying. I've seen the switch to synthetics cause problems in older engines (leaks), and think the time to switch is at o/h. But if you start flippin burgers, next time I'm in the Lone Star, I'll be by for one.

[/QUOTE] I'm not planning on doing the engine,just the tranny.I already switched the rear end over with no leaks or any other probs.

Vette(s): 1975 C3 Red, T-Tops, Black Interior. All I need is time and money! Getting there!

Synth can cause leaks.  When the gaskets wear they can build up a bit of varnish/debris/dirt etc.  This build up can actually help seal a worn gasket or old seal.  The synth fluid does a better job cleaning, and flows better.  If the seals/gaskets are worn, the synth can clean the stuff out, and the better flowing synth can then leak.  If this is not the case, it won't leak.  Crapshoot time.  This is true of engines as well transmissions, and gear boxes and axles.  As Clint Eastwood once said "Do you feel lucky?"

Well,for the record...it took 14 qts to refill with synthetic after flushing.But 10 qts of regular everyday stuff was used 1st, until everything ran clean. Seems to be operating smoother now

Vette(s): '68 Black Conv. Matching 327/300 4 Spd. P/S, P/B, P/W, Tele, A/C

Although my Vette is a 4-speed, for the last 40k miles I always change the ATF wen I change the oil in my personal car (Olds Bravada).

At about the 80k mile mark, I realized that the oil had been changed about 20 times and the ATF never was.  It didn't smell bad but it could use a change.

I dropped the pan, changed the tranny filter and I drilled a hole in the pan & installed a drain plug.  The way I figure it, as I introduce more of the new ATF into the tranny @ each oil change, I'll end up with as close to a complete change as I can get.  Hopefully this will extend the tranny's life, I'm pushing 140k now.

Yeah,next time I need a change I will either drill a drain hole like you,or maybe just buy a better pan with a plug already in it. I was planning on either this time,then I forgot about itC3RVETTE38617.7584375
