Trans Slips when cold
 

in my 97 se, the trans just doesnt wanna move if its cold. after about 2 mins or so, it runs perfect. the only thing ive checked so far is the fluid level. thats fine. but the fluid is pretty discolored. its not really red anymore. knid of the light pink/ tanish color. ive put less than 10k miles on it. and it has 175k right now. so im leary of a fluid change.

what if i just do a filter change and only replace the 4-5 quarts that i lose from dropping the pan, will that cause problems? rather than a total flush?


and just a brainstorm for worst case scenario, but will a 65 be a direct swap for my 60-e?

I've never seen a trans fail from a fluid change unless it was failing horribly already. Drop the pan and do the flter. That may help.

The 65 is not a direct swap. You will need a different harness and PCM.

Frankly, I feel the 60E is a bit more reliable and has fewer problems on average than the 65.

Wes, Go ahead and change out the filter and fluid... The Trans may be about done for.. Sounds like it bit a seal or the Pump is getting weak..

For everyone out there..

This is one of the reasons I like to see the Trans run cool.. Say 150-160F at any given time.. Once you hit 200F you are begining to cook the fluid and internal seals, over the years these seals will get brittle and break or crumble, creating issues like listed above... Its amazing what a difference temps can make over the life of the trans..

Let us know how it goes Wes ;)

the fluid was pretty dark. i didnt smell it, and definitel didnt taste it (Bill), but heres what it looked like. i think this is the first time it was done.

and i didnt have time to drive it to see any change, it was x-mas tree day with the fam, and hockey after that. so ill have to report back on that.

on the way, i saw an orange bonne on fire. sad sight. tried to get a good pic, but my girlfreind was too slow with the camera and all i caught was the smoke.

Wes that has me slightly worried...

Thats a bit on the dark side... Not totally Brunt... If it was badly burnt you would have been talking junk about the smell... Trust me..

It looks like the fluid was never changed, and the trans was overheated... Now that you have changed it, keep an eye on it and make sure you do not develop any slips or anything...

I have half a notion to tell you to bypass to an AUX trans cooler

im gonna dive it for a lil while, and if it ends up being ok, i will put an aux cooler.

but if/when the time comes, do you use both coolers, or just bypass the rad cooler alltogether?

Generally they are run together...

But if the trans ends up ok, I would tell you to get a thermostatically controled cooler and Bypass the Radiator altogether

a controller? so it doesnt cycle all the time? like a e-fan controller?

Not quite...

There are coolers that will bypass the fluid flow when the trans is cold, this way the trans can heat up a little as it should... When the fluid reaches a certain temp the Fluid will begin to flow through the cooler... So say at 160F the trans fluis would be flowing through the cooler cooling the trans fluid.... Say at 20F, the fluid would bypass so that it can warm up.... You don't want the trans too hot, but you don't want it frigid cold either ;)
