need help! Transmission issue

[moparviper]

i had another thread going on my quarter mile time and how slow i was. what some members had said is that could have been my shifting witch led me to look at my transmission fluid level. once i determined that was at the proper level. i started looking through my service record and i see that valvoline had put valvoline synpower 75w90 GEAR oil. from what i had read on here is that gear oil is not good for our transmission. i need help on what to do. please any advice is helpfull.

Drain that sludge out and put some Syn. ATF Some members use Mobil 1 ATF,I use this.

It would be a little costly...but I would drain ,fill with ATF put some miles on it and repeat to get all that heavy stuff out of there. (Mobil 1 ATF here)

I agree, better change it twice.

Luckily my brother works at Valvoline and i was able to take my truck up there and they determined that they had made a mistake and put the wrong stuff in there. So what they said they would do for me is put the correct fluid in there and let me drive it for a little bit. And if that doesnt fix it they said they would take care of me. And im assuming they mean there gonna buy me a new transmission. But from what i understand once a syncronizer is bad there no fixing it. Is this correct?

Is the transmission grinding when you shift now? If it's not, I would think it will be ok, once you change the fuild (a couple of times) to get the gunk out of there.

Yup, change it,drive a few hundred miles, drain and fill again with ATF.
I know you said you "changed" clutch brake fluid, but is it bled? It has to be purged of old fluid and air!! Not just changed in the reservoir!!!

 

[moparviper]

Yes it was bleed out completely and now i can feel the clutch earlier. And no its not grinding but it strughles going into gear and gets hung up when shifting.

 

[viperhauler]

technically... you can change one synchro, but it's stupid... you have to disassemble the whole trans anyways...

i'm surprised they fessed up to that to be honest...

i used mobil1 in the oem trans for 100k miles... then went to redline in the built trans...

Have you loosened the bolts on your B&M and made sure the ball is centered? Give it a try, it might help.

I have a similar issue with my trans, the gears hang up a bit too and when I first start up my truck the shifter feels a little stiff to move around but after a minute it feels beter. I have the original gear oil in my trans and OEM shifter. I will do a oil change and put some ATF and see what happens.

Im taking a look at my b&m shifter now but how can you tell if its centered? Just by looking?

It's more of a feel thing. Guys do you remember the instructions on this? In neutral to tighten the bolts? (it's been a while!).

 

[viperhauler]

barely loosen the bolts... run through the gears and make sure it's smooth in each one... then retighten with the shifter in neutral...
