Not everyone follows their owner's manual like a bible. To me, changing fluids to non-OEM brands is personal choice.

For starters, I don't use 5w20 because I want a thicker 5w30 or 10w30 full synthetic oil. I'm going with either Redline MTL or RP 75w90 gear oil based on all the reviews I've read. No one has had one bad thing to say. When it comes to cold starts, let your car idle for a few minutes then drive it. Shouldn't have any issues. For the rear end, Ford says use 75w140. Ok, I agree but I'm going with RP instead of OEM based on more reviews I've read.

 

^^^^do you have a Boss?

 

I don't. Just get annoyed when people think everyone should stick with OEM fluids all the time. Nothing against them, it's just personal choice.

 

tracked the heck out of the car Saturday. the clutch pedal stuck once late in the second sessions and i was hauling **** at that point. fried the factory pads to the metal backing and burned half a tank of fuel in 30 minutes mixing it up with a modded evo and a porsche GT3. im glad to say the three of us ran neck and neck the whole time with us all right in same times.

anyway, the transmission did very well even on high rpm shifts after the fluid swap until that second session when it got hot. again going form redline 7500-8k shifts to 6500-7k fixed the shifting issue.

 

Did you ever try the JHR high flow clutch line?

no i didn't. i have thought about it but have been hoping to hear form someone else if it works.

 

We were all hoping to hear from you that it works.

 

ive asked a couple people and shops what it would cost install, but no one has been able to tell me. i don't want to buy a $100 part and find out the install is $300 or something. i am also not that hopeful it will work. i emailed the company selling it with questions and they didn't even bother to answer.

 

Rick, Do you know if the other member you refer to was having shifting problems before switching to the Redline oil?
