huh....?

this isn't motor oil.. this is a tranny oil thread.

 

wow. i havent read this thread in a while, thought this was the synthetic motor oil one. Im an idiot!

 

To answer your question..........no, there's no harm.

 

Nah, going back to conventional oils after using synthetic won't hurt anythning, just dont mix conventional/synthetic oils.

 

How hard is it to remove that reverse sensor? Does it pull out or twist?

I am NOT refilling this thing through the fill plug again.. That was the worst.

 

1 1/16 socket is needed.
haha, you should have never done that. Just extra work. It's really easy. Here's the DIY:

Thank you kind sir!

uhh...

you linked the thread to itself...

 

OH.................

 

DOH!

 

I had my local mech swap it out for me for $20...I think it was worth it lol

 

I replaced the Royal Purple MaxGear with MT90 and things got a lot better (considering the Royal Purple made the car much worse than it originally was.)

I can't really say that shifting is better now with the MT90 than with the stock fluid, but it is smoother once warmed up.

I think I'm gonna give this one last shot on my next oil change and change the tranny fluid again using redline 75W90 NS fully synthetic. This is a gear oil that meets the tC's GL-5 requirement (something MT90 does not do) and has no friction modifier in it - the stuff in the Royal Purple that f*cked my day up.. I think.

I took my car to the dealer with regard to grinding gears and clunky shifting when cold and they said that nothing is out of the ordinary - BIG surprise.

 

As a mechanic, I can say that about half the time a customer comes in with some weird noise or quirk, the car runs perfectly normal. Just one of those things I guess...such is life, lol.

 

But then some mechanics just don't want to be bother'd with guessing games. (not you) but most. Some mechanics drive broken down work trucks so when they get in a new car with a small problem there like " Wow this cars great runs nice ect. ect " I'm just saying that i've had my fun at dealerships and come to learn that most mechanics should be called Parts Changers!

 

I went to Advanced Auto Parts... the guy looks up the Trans Fluid/Gear Oil in a book they had... and came back with 4 Quarts of Valvoline 80W-90 GL-5 Gear Oil. Is this the right kind or should I return it?

It's this stuff:

i had installed the ingalls damper, the nst shifter cable bushings, then the creative compacts short shifter. shifting was inproved greatly, mostly by the short shifter.

but then i figured i'd spend the extra $30 and do the redline MT90 as well and it was totally worth it. with all these mods put together shifting in my car is perfect. highly recomended.

 

I looked at a chart that compared different weight oils, and it seemed like he 80W was a lot heavier than the 75W that the car calls for. I would return it and order some Redline to be safe.

I found a place that sells Redline 75W90 NS online,

Could you be my test subject and order 3 qts of the 75W90 NS and see how it runs??? It should work better than the MT90 considering it fits the cars' specifications 100% unlike the MT90.

 

This chart is pretty much the same as the one I looked at. Royal Purple gave me their viscosity chart because they felt bad that their gear oil nuked my car, but I can't find any links to it, so I searched and found this. Look in the gear oil column and you see the major difference between 75 and 80 weight.

Our car requires GL-4....GL-5 will create excess noise and wear on your synchros.
