3rd to 4th gear slippin'

Okay, so when in half or full acceleration, from 3rd to 4th gear, the transmission slipped for about a sec.. only between 3rd and 4th.. all the rest works fine...

Somebody told me that maybe it was the ECC.. What is the converter clutch do exactly???

And btw, its a 2000 SE Intrepid with the 2.7L engine.. 254 000 km.. Transmission fluid color is red(3000 km since flush) and I use only the Mopar kind ATF or AFT+4...

Also, is it expensive to fix the problem??

btw.. the dealer change a hose on my tranny and instead of putting back the same fluid, they put an other one with dexron on it.. is this maybe the problem.. so maybe if I only change the fluid, can it help??


Sorry, I just checked my bills ;)

Throw some Lucas Oil in it. It prevents slippage.

that's a major no-no on Chrysler transmissions, they are very sensitive to the type of fluid you run in them, no additives or any other fluids etc. Katana1981, if the dealer put Dexron in, you'll need to drain that put ATF+4, mixing those transmission fluids is like mixing oil and water.

so what you say theFreakNasty is that maybe the dexron is what making my transmission to slip?!

If you say its possible.. I'll change it right away!!

well, it's possible, but in all honesty, I'm not 100% sure that'll be the permanent fix. You have high mileage on your transmission and the average life of transmissions is usually between 150,000 to 200,000 miles, and you're in that range right now.

Thanks for replying..

Another question: I went to a transmission garage and the guy told me that he has pull off all the clutch before getting to the 4th one.. so Do you think its best for me to change the gear or to change the transmission?!

btw, a rebuilt transmission is 1500$ taxes included installation included with a one year warranty..

You can't really change the gears, unless they have been torn & ripped to shreads. Honestly, get a new tranny, though it's quite pricey, but in the long run, it'll be to your advantage. It's under warranty so if anything goes wrong, though it'll be an inconvience to you, you won't have to pay for anything that went wrong.

thank you FreakNasty82.. What I'll do is wait till the fourth gear die 'cause you see today, I drove for about 400 km and it didn't slipped at all.. so I'll wait and for 1500$ CAN I think I'll get a new tranny!! Thanks a lot

another thing I thought of that they can do is go to a dealership and have them do a CVI (clutch volume index) and see what exactly the values are. Also, have them do a pressure check.

i would change the oil with ATF+4 a couple of times as you cannot drain the torque converter so drive it between oil changes and then asses your situation oil is cheap

thanks.. For three days now, the tranny didn't slipped at all.. I'll try to take an appointment with my dealership for the pressure check etc..

Last time they told me that if my engine light doen't light, they won't be able to find any trouble on my car, isn't right?

that's not necessarily true, if you go to a Chrysler dealership, a factory-trained tech will be able to spot a potential problem if he hooks up a DRB III scanner. For me, if I'm reading the CVI values on the DRB III, I can tell when a transmission needs a rebuild based on those values on the screen.

okay good! Its been a week or a week and a half since I've put some Lucas in my transmission fluid and since then.. no more slipping!! i'll wait a bit and if the problem's getting back, I'll go check it at a dealership trans tech. ;)
