Just went to pick up the kids and it slipped and caught on a turn. Then it got worse over the next one mile. Reving and no go.
I drove it back home in reverse. Added 2 quarts of tranny fluid that looked low. Still same problem.
103,000 miles. I changed the tranny fluid and filters at 80k.
Is my tranny shot?

I would also appreciate any model # info on the tranny.

Thanks in advance.

 

It's a 4R100. It is also dead.

 

1500 + 1000 for steel gears vs the aluminum ones...I forget what the guy said they were called.

Anything else recomended while the rebuilt is on?

I'm looking to keep the truck another 3 years for another 60k. I'm at 100k now.

 

The tranny in the Excursion is still running strong at 182K miles. It's had synthetic since 165K miles. More recently it's gotten a large tranny cooler and in-line tranny filter.

The tranny in the F250 was toast at 83K miles and a $2K Ford rebuilt 3yr/36k mile tranny was installed. Did regular flushes every 40K miles and had synthetic installed at 220K miles. At around 100K miles added a large tranny cooler and in-line filter. At around 150K miles added a tranny temp guage and three times it got hot and it was shut down before any damage was done. At 249K miles while towing in OD (rarely ever tow in drive and it tows very heavy) the OD started to slip. Current mileage on truck 250.8K miles but it's going to need a tranny to lower RPM's at high way speed to save on fuel mileage. At time of slipping the $2K Ford rebuilt tranny had 166K miles. Now the same tranny is 3yr/75k mile and still cost's the same. Going to put another Ford tranny in but may order a built torque convertor.

 

I believe he said Planitary gears????

Thanks for the info Dougger.

 

Well here's the low down on my tranny. I thought it was time for it to go as I've heard only bad things bout our trannys. But I caused it do to negligence.

My shift wasn't going into park, and so I would use the parking brake and start it in neutral.

Call it lazy but I just never got to it, thinking it was a shift cable or some sort of linkage going bad.

It was caused by a couple of lose bolts under the dash, supporting my steering column. This caused this mechanical valve in my tranny to not engage fully when in drive. In turn this caused my tranny to get approximately 25% of the oil needed to run properly.

After my procrastinating for the passed 6-8 months to fix this little problem, (which got progressively worse) my tranny went.

Lesson learned and hope this helps someone.

PS. $3,500 for the rebuild including....Planetary gears, spragues, new valve, and torque converter.
