trans noise

i put in my sm 465 with the np205 a wyel back and thare was a small leek at the t case adapter plate so i pulled it and resealed it, not leeking now but now once i drive for a whyel the trans seems to get lowder thay are bowth full i used gear lube in bowth, this wasent haping before

when it hapened the first time i drained and re filled the trans and t case, the gear lube looked ok it was onley in for about 4 howers, and that seemed to fix it but then today i drove it for a longer tine and it started making noise agen, it dose it in nutral with the clutch out or costing in gear

it allso gets harder to up shift to therd, it dosent seem to be eneything to majer thares no metel in the oil and it dose shift just wish i could get rid of it

do you think synthetic gear lube would help?, iv been useing 80w90 mabey i should try like 75w140?, mabey the gear lube i had siting in the gerage got some crap in it?

im gona drain and refill it agen tomarow at work so let me know if i should tru somthing elts, should i run a pint threw the trans and t case before i fill them to kinda flush them?

thanks gies, this problem is relley geting to me

Re: trans noise

it sounds like more of a clutch problem than a transmission problem,do you replace the clutch? if so did you replace the throw out bearing and pilot bearing?

Re: trans noise

ya i replace the clutch, presher plate, throw out baring and pilot bushing and hat the fly wheal turned, iv doune a lot of clutch jobs and never had a problem like this

i know it sounds like it could be the clutch from the way i described it but its the trans, ist moste notisabel when your stoped with the truck in netrel then it seems the lowdest if you push the clutch in and nothing in the trans is moving the noise gos away

it seems like the trans is geting to hot and the gear lube is thining out to mutch, when i checked the gear lube the fist time i heard the noise the trans was pritey warm and the gear lube felt relley thin

should i try heaver gear lube? if i should what kind? i dont want to use to thick and hur somthing or have it to hard to shift

Re: trans noise

Have you been able to figure out why it's getting so warm the gear oil thins out too much?

Seems like maybe there is some pressure on a bearing or shaft that wasn't there before you fixed the leak. Just a guess.

Re: trans noise
