Very Bad Vibration

[dsmreck]

Maybe one of these guys who say building a trans is cake should chime in. Is the clutch properly adjusted? May have something to do with the clutch acting funny. If not when the trans is out. Grab the input and out put shafts and wiggle wiggle jiggle. Sorry I'm not more help but that's what I would do if it was mine

No play on the input shaft. Output shaft has it's normal in/ out play. I'll take a pic the axle I was mentioning later.
Going to either grab Blake's or Mark's driveshaft and if it still does it then the tranny will come out.

If it is only under load it could be a driveshaft u joint. Swap driveshafts like you plan on doing, if it is still there after I would check the trans shaft bearings. It sounds like a bad intermediate shaft bearing. Pop the end cover of the trans off quick and check for play on the end of the intermediate shaft. You can fully inspect the outer input/intermediate shaft end bearings with trans in car but you have to pull the second section of the trans case after the end cover.

^ i wish i knew that much about tranys

I feel like I would mess something up haha but I will try the driveshaft and report back. Thank you!

So I just unbolt the cover and will be able to check for play? Nothing will fall out like those 2 oil things will it?
Also wouldn't u-joints still cause an issue no matter acceleration or deceleration?

Does it get worse as you get closer to 5th gear?

[mark4g63t]

it will vibrate sooner..so yes? First it wont do it till like 3k in 3rd it will vibrate as soon as I give it any throttle.
I feel like I keep contradicting myself whether it's rpm or speed related lol

Often times under load only. If there is play in a u joint it can cock under load becoming misaligned and therefore unbalanced causing a vibration on accel. Usually regardless of the gear just load. I don't think this is your problem.

Because it is both rpm and speed related and mainly load. To me it sounds like your describing a bad intermediate shaft tapered roller end bearing.

^ saying this I'm assuming the vibration is just the roughness from a bad transmission bearing vibrating through the car under load. And that all your driveshaft angles, u joints, and cv joints are good.

Did you swap driveshafts yet?
