Hey y'all, I took some time to change my gear differential today. It took me forever because I didn't have the right tool. I went to Sears to pick up those big 23 and 24mm socket wrench. Anyways, afterwards I took the car out for a spin. It was nice today. A little cold but no rain Top down, I drove the car until got to 3 bars. Took the car into first gear and almost redline it, then as I pulled into second gear, it felty a little notchy. I thought it was me not pushing the clutch in deep enough. Tried again and same result. Is this normal when you go from redline from first into second, it gets a little notchy? I've never redlined at any gear before. Thanks My car is resting in the garage now. Just checked the oil and it's still at the high mark

Even if you have 3 bars on your engine temp, your transmission temp is still cool, unlesss you have been cruising for a while. The notchyness will go away as your transmission/oil warms up.

 

Twisted: Why on earth do you think (as you seem to) that either the level or temperature of your engine oil have anything to do with your transmission??

I, too, am confused about what you're talking about otherwise. What exactly did you change? The words "gear differential" together really don't make sense. I assume you changed either your engine oil, your transmission oil, or your differential oil. The engine oil lubricates the internal parts of the engine. The transmission oil lubricates the gears that multiply (and divide) the rotations of the engine so you can move the car efficiently from start to stop and start again. The differential (often called the rear end) is a set of gears and other stuff to turn the rotations of the engine through the transmission at a right angle (so to speak) so the rotations can turn the rear drive wheels. There is more to it than that, but that's it essentially.

You should really learn more about your car. It'll help you understand how and why it works and how and why things can go wrong.

 

my question has nothing to do with the rear diff. fluid change. I just did it today just because I had time to do it. I took the car out for a spin afterward to get the fluid moving. However, I notice a notchiness when shifting gear from first to second. I know the notchiness has nothing to do with the diff. fluid. Just curious if anyone had experienced the notchiness when shifting from redlining from first to second. FORGET ABOUT MY COMMENT ABOUT THE DIFF. FLUID. That was just an event leading up to my discovering of the notchiness. Again, it may has nothing to do with the shifting gear.

 

The tranny is definitely notchy from 1-2 when it's cold out. Not sure how cold it was in your case, but it should smooth out as the trannys gets a little warm to thin the fluid. I'm not sure about whether or not mine does it from a redline shift, I'm pretty light on the gas till about 5 min after 3 bars on the temp gauge. At this point I'd say your car seems normal.

 

Changing the tranny fluid helps a little bit with the notchy feeling. To answer your question, yes it is normal to have the notchy feeling.

I used valvoline 75w90 synthetic diff fluid.

 

Then you can eliminate the diff fluid change. It has been reported that when someone put in very thick fluid in the diff, the shifting was adversely affected.
