Okay so the other day, and yes this was dumb but a pretty girl was calling, i went flying down the interstate 100 plus for about 7 minutes straight never dropped below at least 90. which was 3000 rpm plus
Then when i get to her house my tranny started shifting rough, like first second shift was squeaking tires kinda rough, all the shifts were super hard, so we get to the eating joint and i try to enjoy my burger while worrying about my baby. I go back outside and it drove just fine and hasnt acted up since.
97 4l60e 3.8
Thoughts?

 

yep you called it right. everything was heated which expands and clearances change. would be a good idea to pick up a good cooler to add to the system. may also want to change the trans fluid in case it got burned. are you using synthetic?

 

I think its stock fluid, my gradfather says you never change trans fluid cause the first time you open it up it will start to go downhill from there. But im planning a change anyway. What fluid is good?

 

I also want a trans temp gauge so i can watch it from now on, do they make a pillar gauge holders?

 

You may want to take your grandfathers advice...

 

Elaborate please?

 

yes most parts sites have them http://www.thunderracing.com/shop-by...-Pods_170.html
some have used the cd holder spot to mount gauges at.

 

I'm way more inclined to believe that your continuous "spirited driving" could have dislodged some sediment to make a valve in the valve body hang up, or you could have had a stuck shift solenoid. 3,000 rpm's shouldn't hurt a transmission, and if your fluid is burned because of it, you have other serious tranny issues. If you've never changed the fluid/fiilter, now might be a good time to do so.

 

really old trany fluid can gather metal particles that help the clutches to work. if the trany is getting close to failure a fluid change can speed up the failure by cleaning the particles away. on the other hand if your trany is in good shape and you dont change the fluid then the old oil will allow wear to the parts and cause early failure. can go either way and lose or win. lol. i just change the fluid on new to me used cars and figure if it goes then it would have anyways. you can do a old style change and drop the pan and change the filter. that leaves some of the old fluid in there, then you at least have some metal particles in the fluid.

 

I do drive hard, all the time. So i do expect the car to give up eventually, Its a 100000 mile motor and everything, how long can i expect?
