95 Manual 5spd fluid

 

Hey folks,

I've been pretty quiet for a while but I've been able to start tackling some EV projects and I have some questions for the group.?

One thing I've wondered is if this is the best place still to post questions.? There seem to be more forums out there now and Samba is more active with EV conversation as they age. Facebook groups seem to get a ton of traffic but not quite as expert advice.? Where do you find the best information?

To my topic, I've been battling with my 210,000 5spd being hard to get into 1st gear for a while and last year 5th gear started to not want to mesh up easily.? I replaced all the linkage bushings again and really paid a lot of attention to the adjustment of the shift rod and it still wasn't as good as I was hoping.??

I decided to change the fluid since I couldn't remember when but I was sure that I had changed it in the last 100k/15 years.? I discovered that it was low (I was sure I had checked at some point) and the fluid was quite nasty. It looked more like dirty motor oil and there was a fair amount of nastiness looking in the fill hole.

I refilled with the Redline fluid that GoWesty sells and have driven about 10k on it since. It feels good and goes into 1st consistently and easily.? 5th is still a difficult speed meshing of the syncro to get it into gear, especially after it warms up.

I'm curious if anyone has had trouble with the Redline oil over VW spec oil?? I have a faint memory of using an aftermarket oil in my Jetta TDI manual and I didn't like it and went back to stock for similar reasons.

Also, I'm curious if anyone has ever put Seafoam or similar in a manual trans to clean it up?? I've never seen anyone mention it.

Thanks for your help and I still follow all the posts on this group as it has certainly saved me over the years, not to mention the files section.

It's not necessary to "clean up" the transmission. You could try a different spec of gear oil in hopes of better synchro action, but chances are, they are just worn, and the only true cure will be tearing down the transmission and replacing the synchro rings.

Redline MT90 is probably what you used, and is pretty good stuff. There's also redline MTL, which is a bit thinner I think. I've had good luck with Motul gear lubes in terms of smoothing worn synchros, but again, if they're worn out, the only true cure might be replacement.
 

Thanks for the reply Josh!? I know you're right and I'm avoiding having to rebuild the trans so I was hoping that others had experiences with Redline not being as smooth as advertised, especially since GoWesty's info on their page isn't exactly correct.? They recommend more oil than is needed by more than a quart and their instructions of filling till it overflows are not correct.?

I can't tell if it's MT90 or MTL based on their site,?

I will likely get the VW oil and change it out to see how it looks and if it's smoother.? Again, to put off a rebuild as long as possible.

Thanks!

I've enjoyed the discussion about tranny fluid for a 95 Manual EVC. Mine is running strong but only had 92K miles. Out of curiosity, are parts still available for rebuilding the 5 speed transmission???
