RedLine lightweight GB oil stuffed my 3rd gear synchro!!

[silver_screen]

OEM is good.. Redline is the best

I run Redline oils in my track car and my humble lil civic as well as my old 180sx

Never had a problem. Infact gear changes were much smoother and they never crunched (Use the proper oil for the application)

If you must call Redline, and tell them your situation and they will tell you what oil to use

[turtleEK1]

i had a few crunching issues with my box when tracking it... so i now use oem mtf with that nulon additive and its made quite a difference...

won't make a difference straight away... but i've had no issues with it...

may be a silly question... but how are your torque mounts? if you've been having shift problems, sometimes its because the torque mounts have had it...

[locote]

But its only 3rd gear when upshifing at high rpm, other gears are fine and downshifting is not a prob..
Ill buy the nulon stuff tomorow and see if the problem gets sorted.

who ever told u to use redline, kick em in the nuts

[iijjee]

I've got a friend/acquaintence who is a reputable engine builder in Brisbane. He works on the odd nations cup car and lost of other circuit racers. He informed me that one of the "u-drive" companies in Sydney, which mainly uses XR8's and other Ford V8's and XR6's, was going through g'boxes like they were oil filters. As soon as they switched to Redline - no more g'box problems.

I've used redline in my R33's over the years and I can tell you that Redline Lightweight Shockproof will mask notchy changes and bad synchros, not create them. If it's there now, it was probably being hidden by the excellent dampening effect of the redline oil. Oils is oils and Honda oils aren't made on planet Honda to suit only Hondas. On this planet (at least!) I can tell you there isn't a g'box oil with a better reputation than the one you have recently (mis) used.

Hey, I sound like a redline rep! Anyway I hope this, added to the suggestions about proper techniques, with help people make an informed decision...

I'm with bennjamin here, redline oil didn't kill your syncros.

Also, no matter how many oils you try out, you are never going to 'fix' your syncro problem. Oil will not rebuild metal parts.

Dear David,
Lightweight Shockproof for the gearbox with the gear type LSD. Be sure that it is GEAR type.

Name: david
i am rebuilding a Honda Integra Type R gearbox and retaining the OEM helical "gear type" LSD. which redline shockproof oil will be best for it? if any?

i got RedLine to tell me in writing that they recommended Lightweight shockproof.

What oil did you use?

From the Red Line website.

"SuperLight ShockProof™

A unique product with the viscosity of 75W90 gear oil but lower internal friction similar to that of an ATF. Used when temperatures are not high and when the maximum power output is required such as in stock car qualifying laps.

Used in two-stroke and four-stroke motocross transmissions (often mixed in equal parts with LightWeight ShockProof™ Gear Oil).

Used in 80cc and 125cc shifter kart transmissions.

Used in low-power road racing transxles like Formula Vee and low-power SCCA Production classes (dog-ring type, generally not sycro application where this product can be slippery). "

"LightWeight ShockProof™

A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold. May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.

Used in two-stroke and four-stroke motocross transmissions (often mixed in equal parts with SuperLight ShockProof™ Gear Oil).

Used in most road-racing differentials with moderate power and dogring racing transaxles."

"Heavy ShockProof™

A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities. Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90.

Recommended for Big-Twin transmissions (Twin Cam, '84-up EVO, Knucklehead, Shovelhead, Panhead). Big-Twin primary chaincase should use our MTL product."

Unless you have aftermarket transmission internals and are running a Dogring style gear set you should NOT use the Shockproof oils. I'll be adding more as I look more in to this. I myself use OEM Honda transmission oil.

Edit:

Here is what I would have used. I am in no way a Tech for or associated with Red Line. This is only my opinion.

"MTL

This 70W80 GL-4 Gear Oil (SAE 5W30/10W30 engine oil viscosity) is designed for use in manual transmissions and transaxles. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting. Popular in many BMW transmissions and in most Honda and Acura transaxle applications.

MTL is the correct product for Big-Twin primary chaincase. Big-Twin transmissions should use Red Line Heavy Shockproof, while Sportster and Buell Tranmission should use Red Line 75W90 GL-5 gear oil."

Then added:

"Limited Slip Friction Modifier

Compatible with petroluem or synthetic gear oils, this product will significantly reduce the friction break-in of differentials, reducing break-in temps for as much as 50 degrees F. Limited slip or positraction units will often chatter without use of this product or a gear oil with a similar modifier, so add only enough to eliminate the chatter and avoid making the plates or clutches too slippery."

where is the world is the oil spitting from? haahah the little breather knob? ehehehe

did u fill it using the fill hole.. (bolted in)

read lol

I dont think its the fluid....
why did u use the gearbox breather hole to fill it up ? Probably a big gulp got stuck in there with a big airbubble and blew it all out again = not enough fluid. There is a few good resources about PROPERLY filling up gearbox - including the DIY i did very recently - look -
