I used Redline products in both the tranny and rear of my '93 ZR-1 and noticed an immediate difference. Both the tranny and rear were a bit quieter, and shifting improved noticeably.

Anyone using these products in their car? Any reason why they should not be used - for instance, warranty issues??

Inquiring minds want to know...

I have been using Red Line fluids in my Vettes since 1986, and other cars before that. *********Disclaimer********* I will be switching to Amsoil only because Amsoils is giving me the products for free, they want to use my cars for advertising. I have always felt that Red Line or Amsoil are the two best oils made, they both use the best bases that money can buy. I have heard of a ZR1 that had warranty problems with his trans because of using Red Line, that was a ZF 6 speed transmission, I believe his user name on the CF is Team ZR1, that was the only problem that I have ever heard and do not know the full story. I know many dealerships that have installed Red Line products in customers cars.

I use Red Line in everything EXCEPT the Tranny. Both Red Line and Mr. Goodwrench at the dealership said it would not be a warrenty problem...but from the posts I've been reading, it seems like any change in anything could be challenged by GM, if it ever came to that. For me, I'm going for it. Red Line is superior to Mobile One and other stock fluids. My Uncle Jim in Illinois uses it in his race car and told me they tested the rear axel temp before and after Red Line and found that the temp. was 50 degrees lower with Red Line. He also got another 35 degree reduction with a product called "ER"(Energy Release). You can do a search on Energy Release and find their website. A lot of racers use it.

I use both products. I had a problem with some gear grinding in my tranny that was progressing. We flushed out the Red Line and ER, and went back to stock Chevy ATF, and the problem fixed itself. Mr Goodwrench said the Red Line was the problem, but I think the ER is just too slippery for the clutches.

FWIW, that's my experience. BTW, Red Line claims you'll pick up a couple of ponies in your engine and offer better protection than Mobile One. So, why not use it? It's $8.00 per quart.....Good Luck /phpBB/images/smiles/icon_smile.gif

I find my trans shifts smoother, much smoother with Red Line in the trans, almost like a real trans should shift. /phpBB/images/smiles/icon_biggrin.gif
