Tranny question

[86hatch]

OK I have searched around and havent seen this yet. I have a 99 cc F350 4x4 with 130xxx miles and it did this for the second time today. Under a heavy load when pullin the trans starts pukeing fluid beepbeepbeepbeep near til its empty (like 12qts) today. Now has a lil burnt smell but with fresh fluid away I go and still pulls fine. Oh and when it was low the od light on the shifter blinks and the tc doesnt unlock. I put fluid in and turned the truck off and started back and no light light and the tc works fine. I thinking the tc might be shucked or maybe a clutch pack. Im not really sure because Im not firmilliar with an auto trans. Any help will be appreciated!

Thanks in advance,
Jeremy

where was the fluid coming out???? front of the trans, or more center to rear of the trans???

[86hatch]

Its pukeing out of what looks like a vent tube. Also it only does it under 45 mins. of heavily loaded pulling.

that usually indicates an overheat condition, and the first thing i would do is add on a secondary trans cooler. it is tough to say what is causing your problem...but chips increase line pressure, and therefore need more cooling....and if you have a trans problem, you build more friction....and thus tend to overheat the fluid also.....you could have a fan clutch not working properly....but usually your engine temp would be high also......im thinking that you may have either a plugged trans cooler or an internal trans problem, but the extra cooler will not hurt anything and is worth a try.......

And put a tranny temp gauge on it!

Thanks fellas. I just happen to have a trans temp gauge for my camaro Im not using. So what is a safe trans temmp anyway?

The lower the better, right now being cold, mine barely moves! I have never seen mine get much over 200 when pulling, well, alot of weight...let's see 500 bushels of wet corn @ 60 lbs/bu.

anyone else know a average tranny temp?

it all depends on where you put your temp gauge......before or after the cooler. before will give you a better indication of the temp the trans is operating, after will let you know good, cool fluid is getting to the trans......

Around 180-220 would be a normal operating range from experience. Ofcourse since the trans fluid goes through the coller on the radiator is is going to be close to the water temp give or take. I would not go over 220 really. We do not go over 220 and that is with a 3500 stall converter.

What about mounting it right in the tranny pan, good or bad idea?
