I just recently pulled my transmission in order to do some work, but I ran into a snag. once i put the tranny back in and put tranmission fluid in it. I went for a drive and it felt fine, but after about 10 miles the transmission began to grind while trying to put it in every gear!! I'm not using OEM fluid but mobil one 75-90. I was wondering if this could be the problem or maybe the clutch needs to be bled. I have doubts on it being the clutch.

I bought some OEM MTF fluid this morning and IM going to see if that does the trick. I was just wondering if anyone else had this issue?

Also I sold the car in my sig I have an 07 HR with the not so awesome CSC setup.

 

Bleed the clutch. It took approximately 10 miles to grind because the air made its way up the lines to the master cylinder. Stick with Mobil 1 75-90 its pretty good stuff.
