The good ol' 4r100 trany issues

Last Monday on my way from Idaho to Southern Colorado my truck's tranny went

In Denver while accelerating from 55 to 75 there was a very loud vibration sound with moderate vibrations. I pulled over and looked underneath and had a moderate amount of ATF dripping off the rear of the transmission about 2" in front of the transfer case. i was only able to look at the driver side at time due to position off the freeway and could not see right where it was coming from. I had it towed to the boss's in-laws house so i could continue south for my job, But now I need to first know if someone has had the same issue? I know it is a little vague, but its what i have while I'm away. Second Question is anyone know any good tranny shops in or around Denver? Last is if it needs to be replaced any ideas on the right replacement?

Thanks in advance!

Might have cracked the case.

Rear u-joints okay(common reason for cracking them)?

Or it could have been overheated and puked the fluid from the breather.

Well I have read about this. Pull the pan inspect it flush it put a new filter in new fluid and if it fixes your problem you save 3 grand. if not your out the oil and filter.

As far as replacements, there are 2 that are widely recognized as the best : John Wood and Brian at BTS. Being that you are on the out west, most over there go with John Wood (he is in Cali). Brian is down in Arkansas. I'm one of the exceptions to the rule that live on the east coast and still went with John.

Thanks guys. Hopefully I can make it back to my truck this weekend to get a closer look and to see about the simple fix, fingers crossed.

will let you all know. Also if anyone else has some ideas don't hesitate to offer. I appreciate all the help I can get.

Also I forgot to ask, does John offer a shipped swap? South California is a little far for a cheap tow and I can't get away from work long enough to haul the tranny down, and afford it...

I am here in Colorado Springs and I know a place that does general repairs, and they probably could do a tranny too, there were like 4-5 Fords in their parking lot(running ones, owned by the workers there

) so I think they know their way around our trucks... let me know if you want their info, fyi they are probably an hour's drive from downtown denver, maybe more because they are on the east side of the city, 15-20 minutes from where I am at, and I can get to denver in 45ish...
let me know
