My transmission on my 2000 jeep Cherokee makes a ruff vibration when under a load or on a fast acceleration, only does this in first gear and if I accelerate slow it is fine, anybody have any ideas

 

hm, does it feel like its slipping. could be torque converter going out. Try a fluid and filter change. DO NOT FLUSH!

 

It doesnt seem to slip at all, I just changed the fluid about 3 days ago and it was pretty burnt, I didn't flush it

 

so it like vibrates? like jerks you. Its just hard to image whats going on w.o bein there. you know?

Can you describe it any better. Whats vibrating, where its coming from. Ik you said the trans but, could it be a mount? Is the Jeep like shuttering?

 

The vibration almost feels like something is grinding, I can feel it in the floor and in the center console, I was thinking a mount my self, I got under there and tightened some a lil, I was thinking that under a load or acceleration it is tweaking something causing the noise and vibration, but it only does it in first gear

 

Damn Jeeps, they always gotta make noises lol. Im a little stumped, hopefully someone else will chime in. If it was a mount it would do it in any gear.

 

So about 8 months ago I was towing my boat up a hill and overheated the tranny and some boiled out the top, I think that pretty much smoked the tranny fluid, it has to be related, it never did it before that, it kinda came on slow and now if I give it a about have throttle it does the creaking grinding thing

 

Ya I thought the same thing, mount it would do it all the time, makes me think its internal on the tranny

 

ya its gotta be internal. first gear clutch is slipping

 

My brother told me you can go in and tighten it up so it stop slipping

 

Your brother told you to tighten what?

 

He said there is some belts and that they might slip and he said you can tighten the belt up in 1st gear I believe to prevent it from slipping

 

Its a bad not a belt it is recomended when you do a filter change. But I don't belive that's your problem. It sounds to me like a u joint issue. Band adjustment won't cause a vibration.

 

Would a ujoint only do it in first gear?

 

Check exhaust pipe, might be banging on crossmember, makes a bounching grinding noise
