Not are what to do about this. I was driving back from thanksgiving, about 3.5 hours on the Freeway and almost home when the transmission acted like it slipped. I was at a stop sign and the transmission seemed to hesitate shifting down a gear then shifted down what felt like 2 gears then proceeded to to act like it was slipping when I pressed the accelerator. When I let up on the accelerator (less torque) it would shift gears but as soon as there was any torque on it it would act like it was slipping and changing gears. I stopped, shut off the engine, waiting a few minutes then started it back up and it seemed fine for about 3 minutes until we started up a moderate hill to get home where it started to slip in and out of gear. I made it home, started it up a bit ago and drove it around the block with no issue but my guess is that the moment I try driving up a hill it's going to slip again.

The transmission was serviced about 6 months ago & I've not had an issue with the transmission since I bought the truck 18 years ago.

Thoughts and or suggestions on the next step would be appreciated.

Thanks!

An update, just checked the transmission fluid this morning while it was cold. Just registering on the stick so this might be my issue. Not real happy this is low since it was serviced 6 months.

Yes - but need to know why its low. Need to cycle the trans through the gears and reverse after service to have fluid circulate everywhere and get a true reading. Does fluid smell like burnt pizza? Did they remove dipstick tube and not reseat correctly or cut the O ring ? Check when trans is hot. Also there might be a rear seal or pan leak ? Maybe a fittings not tight and sprays when under pressure going down the road in drive — no driveway puddles.

Thats one reason to change your own oils/fluids. Too many post-maint issues, caused by service tech and not reported or corrected. A family member had a service tech forget to drain oil before filling another 4 qts once and it caused loads of issues. Know if your tech is on the pipe...

So I am about to address what looks like small leak on my 83 transmission (Torqueflite 727 3 speed - different transmission then the later 4 speeds). Over time I have worked out the following:

1) Oil level checking is not as straight forward as just pulling the dipstick. Mine can read overfilled after being parked. You need to cycle to get the oil properly distributed. Low oil represents itself on my car as harsh shifting.
2) The oil pan gasket goes to mush and should be replaced with better reinforces rubber type (bought that)
3) Dipstick o-ring goes bad. I think I have a leak here but this has slowed after I started useing the car (been stored for 20 years).
4) The rear seal leaks on mine, but I was not going to address it. It only seems to leak when you overfill and when (for no reason) the torque converter empties itself while standing still.
5) There is a front seal which can fail, but mine seems to be fine

So my plan is to change the oil pan seal and the dipstick o-ring, hopefully this will resolve most of the oil stains and 6 monthly top up. I need to remove the exhaust and cross member to get the pan off and I need to reach one bell house bolt to get the dipstick, hopefully access will be greatly improved with the exhaust removed. At least the range rover has a drainpoint I have been reading that Mopar Torqueflite applications omit drain so you remove the pan full of oil - messy.
