Hello all, My Name is Jim, I am Joes older brother... He wanted me to make a post on here for some tech help.

Recently he has been having some transmission issues. Hard 1-2 shift so he had it flushed on Thursday. When he had that done There was some pretty big metal chunks laying in the pan also amongst little chunks/shavings that was mixed in with the fluid. Now I do realize that it probably was a big mistake to flush it but It probably made no difference because the transmission will destroy itself no matter what because of the damage done to it.

I need some info on these cars as far as what kind of transmission (auto) it is and possibly some model numbers.... We are gonna try to find a used or rebuilt one for the car since the motor is strong. I told him I was willing to work on the car along with him.

Please let me know and I will also snap pictures of the metal pieces.

He needs to know about the original trans in the car so he'll know which used on to buy . . . . Anyone?

I did some quick research, and came up with this. It appears that there were only 2 choices.

Transmission Model: 4T60E (20 BOLT FLUID PAN)
Transmission Model: THM125C (LOCK-UP CONVERTER)

So if it has a lock up converter, you have the THM125C. Hope this helps!

My car (4t60e) has the exact same problem... possible solutions include a stuck throttle valve inside the tranny or a bad ground connection on a shift solenoid

I also heard not to change the fluid in that situation... it only seems to make it worse

I've been riding my tranny in this condition for a long while now... of course, I added Lucas trans fix to reduce the higher operating temps due to increased friction
You might want to check your vacuum modulator...
My trans shifts fine as long as it's kept at or below the 2,000 rpm range during the shift

IMO, when a transmission starts to shift like that, or slip like crazy, or you see metal in the dexron, its time for a rebuild, or a new (different) trans. It will be unreliable and you'll have this "trans demon" looming over your head at every stop light

I agree, but unless you have the exorbitant amount of money charged for the repairs (or buying one and doing it yourself) you're pretty much stuck with a time-bomb (my case )

Thanks, Andrew. I'm sure they appreciate your input, however, they still need to know which trans they actually have so they can proceed.

I thought that the decriptive things in the parenthesis would help them determine what they had... maybe not.

Andrew

Joe claimed there was alot of metal in the fluid. I did find out what the huge metal chunks came from... It is parts from the clutch plates. I specified an automatic tranny as I was thinking that maybe a manual was available..

I think Joe has decided to send it to the junk yard when the transmission goes. He's lookin to get into a 4x4 truck..

Considering the cars other problems, I think that's a good choice.


A quick reread showed me there was no need to post my comment, as you had it correctly covered.

If I made an error (and I'm not saying I did) I won't admit it.

careful norm, you're giving {nameless individual} fighting ammo

Hi 88delta88, all,

Not to worry. If I ever do make one, he won't be able to find it.

Not admiting to a mistake. Knew it was there, didn't think of it.

Surprising, no one posted it before now. Might be more noticeable if the tech area was moved here, but I rarely use either page.
