pyromanic Posted March 4, 2005 Share Posted March 4, 2005 I would like to here everybodies favorite recipies for quiteing down and slicken' up old, notchy 5 speeds. I know that Redline is popular. Which one? Or which mixes? Other synthetics? Lighter? Heavier? (are there rebuild kits availiable for these?) I'm not interested in what folks put in transmissions that are still in good shape, even if it may increase longevity. Just what folks are doing to try to get old, tired ones to act nicer. Thanks, Pyro Quote Link to comment Share on other sites More sharing options...
ballitch Posted March 4, 2005 Share Posted March 4, 2005 im thinking of putting in a quart of ATF for about a 100 miles or so, then refilling with a fully synthetic 75w-140 form walmart, think its supertech or something, like $8 a quart. thats what ima do soon, 3rd gear gets kinda picky sometimes, anyone else have another good suggestion? ~Josh~ Quote Link to comment Share on other sites More sharing options...
ShawnW Posted March 4, 2005 Share Posted March 4, 2005 Rislone for around 500 miles then drain and fill with synth fluid. Quote Link to comment Share on other sites More sharing options...

Is to help "cushin" things internally? Do you think going heavier like that helps? I think Soob says to use 75/90. I been wondering if heavier like that would help with the notchyness.

ballitch Posted March 4, 2005 Share Posted March 4, 2005 the thing about synthetic is it will thicken up at higher temps like its supposed to, at lower operating temps like in city putt putt driving its not as demanding as say off-roading or mudding or high speed car-chase-like highway speeds were the gears are going a million miles an hour, rislone is another good idea i didnt think of that, might not "clean" out the tranny, might damage something also......hmmmm..........ya the 75w-140 is just the same minimum weight oil with extra headroom.....at least thats how i see it... ~josh~ Quote Link to comment Share on other sites More sharing options...
JWX Posted March 4, 2005 Share Posted March 4, 2005 fill it with straght ATF run that for 500-1000 miles ATLEAST, and then put some good syn oil in Quote Link to comment Share on other sites More sharing options...
Snowman Posted March 4, 2005 Share Posted March 4, 2005 I've had good luck with the Quaker State 75w90 synthetic that's been in there for a while now. I'd try the ATF trick then switch to the synthetic of your choice. If that doesn't work, find a good tranny at the JY. Quote Link to comment Share on other sites More sharing options...
archemitis Posted March 4, 2005 Share Posted March 4, 2005 theres no carbon in there, its just metal shavings, i dont think you realy need to clean it out. just drain it. and fill it with good oil, usualyhelps alot. i have mobil1 gearlube inone of my 5 speeds. and i have redline in my 4 speed. some 5 speeds just suck forever tho, i have one that wont go into first untill your completely stopped, even with double clutching.

torxxx Posted March 4, 2005 Share Posted March 4, 2005 sounds like my 5 speed. IF you are going over 5 miles an hour, gotta rev it up to 4 grand with the clutch in to get 1st to engage.. Quote Link to comment Share on other sites More sharing options...
archemitis Posted March 4, 2005 Share Posted March 4, 2005 now that i think about it... a guy at redline told me to run the atf redline fluid in the 5 speed, forever. Quote Link to comment Share on other sites More sharing options...
pyromanic Posted March 5, 2005 Author Share Posted March 5, 2005 now that i think about it... a guy at redline told me to run the atf redline fluid in the 5 speed, forever. I don't get trying to clean these older manual trans with Riselone and stuff. Like has been said, cutting is all that is in them. Flushing with gear oil is good though. I know that later model MT's are designated to run on ATF. But I'd personally be scared to try that with these 1/2 worn out MT's. Seems to me that heavier (only a little) might be better than lighter. ATF seems (to me) WAY to light. I want CUSHIONING in there. Something to take up the slack that has been created by wear. Sounds like synthetic is the best bet, but I wonder how much difference it will really make with a 1/2 worn out tranny. I put redline in one that was REALLY notchy. Felt like a new trans for a 1/2 a day. Then back to nearly shot. Can these be rebuilt? Junk yard tranny are a crapshoot at best. (unless it's from a low milage wreck, and those are hard to find I think) Are parts availiable for the older MT's? Pyro Quote Link to comment Share on other sites More sharing options...
ShawnW Posted March 5, 2005 Share Posted March 5, 2005 Using 1 quart of Rislone in place of one quart of gear oil doesnt hurt it but it does clean the snycros. I have done it to 3 tranny's already with success, a 5spd dual, a 4spd single, and a legacy 5 spd AWD. Quote Link to comment Share on other sites More sharing options...
kay95 Posted March 5, 2005 Share Posted March 5, 2005 try GM syncromesh with motul or redline works well for newer subys 2 quarts of GM SM to 3 quarts red line or motul Quote Link to comment Share on other sites More sharing options...
baccaruda Posted March 6, 2005 Share Posted March 6, 2005 someone - i think it was andrew/hondasucks - said the pros like half mineral and half synthetic in the trans.. Quote Link to comment Share on other sites More sharing options...
