1998 Lumina, 4t60e slipping

[1979lee]

Well after 169k miles i think its rebuild time for this 4t60e.

ive put 95 k on this car with no real problems. the engine runs well ,still on the factory original lim's.

anyhow. shes slipping in 4th gear(overdrive) and today a little in first gear.

if i give her a little shit the slippin' goes away(more throttle= more line pressure me thinks).

its shifts through the gears fine and it stays in gear fine, reverse is instant.

but when shifting into drive its about 3/4 of a second delayed.

 

a little history on this trans,car. the prior owner was the county of san bernardino california (deserts, mountains hot temps, hills, and by the way the cars undercarrage looks it went offroad a few times. i got it in 2006 for $ 3500 (yeah i paid too much) it had 75k on it then.

the county must haced servied the tranny at 50k or so (it had a FILTRAN filter)

but it ran great and shifted perfect till about 2 months ago.

i had noticed something odd about the shifting , it just didnt feel right.

so i dropped the pan did a fluid/filter change(dex 3).

now here it is a month later and its slipping and the fluid is darker and it smells burned. so ok then i suck out enough too add some lucas trans stuff.

(it didnt help made it worse).

last night i pumped most of that crap out and put in 5 new qts of dex 6.

it was better for about a day now it slips again now in 1st.

 

Sorryfor the long winded(gasbag) post.

any ides or Prayers? for this 60e

oh by the way no check engine light is on and no codes in the comp

I would call around to a few junkyards and see if they have a low mile trans for you

Your clutch plates are fried buddy. That's the burning oil smell. That trans needs a rebuild, its really that simple.

[Definately R/R time i hate to say. It only takes a couple of seconds to fry a clutch pack during a soft shift/slip.
