Ford Tranny Woes

[pluto]

Ok, same truck different leak. It is the 97 powerstroke with the Auto, It seems to get hot very easily. I have had multiple problems with it boiling tranny fluid out when I tow. I do not tow in overdrive either. I had problems towing my gooseneck with two jeeps on it, so I put in a cooler that I believe was rated at 40K lbs. Well it still heats up, today it made me mad, I towed my new gooseneck horse trailer home, probably 3500 lbs with overdrive off and maybee 30 miles at around 55mph. when I got home I looked and it was spitting out tranny fluid. It is a relativly new tranny, mabee 10K on it. the truck has about 120k. I am pretty sure not everybody that drives these has to put up with this bs. Any advise would be great. Thanks

Who built the new tranny? The Ford reman's have a terrible reputation, though mine from 2001 has 90K on it. Do you have a tranny temp guage? How hot is it getting?

some shop in castlerock that is not a tranny shop. It was done by the old owner jut before I bought the truck, so there is no warrantee or anything like that. I don't have a guage on it I was thinking about putting on a bigger pan and guage but if it cant tow 3500lbs now I am not sure that a bigger pan will help anything. I did put mobile 1 synthetic fluid in, but that doesn't seem to help.

would say you defintly need gauge. mine was doing the same thing before i rebuilt it now im towing 22,000lbs total weight with truck. and i can even tow in od and temp only gets to about 190. 97 powerstroke, auto, with 6in lift and 36 in tires, 488 gears. original trans pan with aftermarket trans cooler. need tomake sure fluid is going from trans to radiator then to cooler and back to trans.

I wish I could do that. Were did you put the temp sensor, what guage would you recomend, I was told I needed a diferent pan to put the sensor in. and how can I check if the fluid is going through the radiator and the tranny cooler. would it also help to get a new cooler that has a fan built onto it? thanks

just ran procomp gauge from 4 wheelparts. there is a plug just above shifter linkage and that is where my gauge is actually reads about 10 deg higher then fluid temp is in pan. if my gauge is at 200 i can get out and with temp gun pan will be 190. its messy but you would have to unhook lines and run into bucket ahve some one crank truck and see which way flluid is going. make corrections to line routeing if needed. dont think cooler with fan is needed as long as it is getting good air flow from front of truck. id say if thats all good you may be looking at a rebuild unfortunatly.

I feel like a broken record on this and I am not even and Auto tranny guy. :) The best tranny you can get for a PSD is www.brianstruckshop.com and I am sure he'd be happy to help you diagnose your problem as well. Top notch guy and many many PSD guys can vouch for that. You don't have your location listed, but there are local vendors of his trannys near Denver.

i have the 97 4 door 4x4, 3:55's. Mag Hytec rear diff cover too.

i got a MagHytec pan, with temp sender (it comes with the bung), a cooler out front, BYPASSING the radiator segment (send the tranny fluid to its OWN cooler, having it next to the hot radiator fluid doesnt help).

i dont tow often, but have towed a skid steer from time to time (trailer and skid steer ~9400 lbs.

my gage read fine
