Boom ... One less 4R100 in the World

[Doghead]

Well it finaly happened, My tranny scattered it's self. It was just a matter of time I guess. Things will only take so much abuse before they complain. It's the first tranny I have ever heard go with a real bang though, it sounded like someone hit it with a sledge hammer. Tranny shop can't fix it untill next week but I wonder if you guys have any ideas what goes bang like that.

How many miles did the 4R100 run to till bang?

The truck has 264000km on it or 164042miles. I figured that somting was up when it had a steady drip anytime I towed something. I took it to a few different tranny shops and they all said that I must have boiled it over but I think that it was a seal that was leaking.

164k miles is better than the average for 4R100 transmissions but you got good miles out of it

Grining Ear to Ear most of the time and praying for help the rest of the time!!!

sounds like the front pump seal was leaking... happened to mine - got that fixed in November, then a couple weeks ago, she went bye bye... turns out I have an early build 2001 (aug 2000 thru march 2001) with the mechanical diode tranny that just happened to last longer than expected and was esentially a ticking time bomb...

good luck on the repair/fix! are you building it up or just fixing it to stock?

Failure is the perfect oppertunity to improve on a weakness. Im building it up. A while ago I asked on the forum if any one had heard of the North American Powertrain Components "Heavy Hauler" NAPC- Engineered Beyond the Gears™ - Heavy Hauler®
No One had any comments about them though.
This is the Unit that I am thinking about upgrading to. If not this unit then I will be putting in a BD Valve Body and Torque Converter.

Why Not give BTS a call? Best 4R100 guy there is.

BTS is a long way from here and getting somthing like that over the boarder in to Canada would cost a mint.
To make the week even better I rearended a Dump Truck in my Company truck this afternoon . What else is going to happen?

wow man, that sucks! Seems when it rains it pours... I went thru a stretch where I totaled my maxima (92 model) after hitting a deer comming home from work ( was an hour drive one way) at midnight in the middle of November, then wrecked my work vehicle in the middle of a blizzard (we do'nt get those in Oklahoma....) in december, then in Jan, I flooded out the replacment nissan sentra I had prchased by falling into a HUGE pothole in a trck stop parking lot... 3 months, 3 vehciels damaged... yah -- it sucked...

then here 2 weeks ago - I jacked up the nissan maxima (had been rebuild) trying to redo the front end axles, crushed my $300 phone in the tailgate of my truck, then lost the transmission in my Ford 2 hours from home...

Needless to say, I feel your pain.. and it can only get better!


as for your trans, I have not heard of that company, but BD seems to be very well liked up in Canada, although they are a tad expensive!
