400 E transmission tranny is slipping?

400 E transmission slipping on highway when going 50-60 after 15-20 min, it sounds like it is slipping into 2nd gear maybe and the rpms will reach 5,000-6,000 when i try to maintain 50-60 mph. If i park the car the problem will go away temp. but will return when i drive a long stretch. what should i do first? flush all fluids? tune ups?

Check the fluid level. Make sure the engine is warm and engine is idling. If the fluid level is fine then try changing the fluid and the transmission filter. *Note: if you take it in don't let them give you any Jazz about metal shavings in the fluid. It's a scam. Metal shavings in the bottom of the pan is normal tranny wear. Tell them to just changed the filter and fluid and be on your way. Hopefully that should correct the problem.

2001 Dodge grand caravan sport. Transmission slipping/ jerking. Seems to run only in second gear... still slips and jerks. Smells of burnt trans fluid and the level is low on the dipstick.

I need a little mor info. But the reason for the being stuck in 2nd gear is because when something goes wrong with the tranny. it goes into "LIMP" mode wich keeps the trans. from shifting out of 2nd when you are going forward. It does sound like your trans. is gone out though.

1999 continental tcc code

Sounds like the lock up torque converter is slipping based on your description of the problem. i estimate roughly 1,250 dollars based on 400 dollars for a torque converter and fluids, and 10 hours labor at 85 an hour.

Voyager transmission problem

Sounds like you need a solenoid pack to start, and possibly a service. If the tranny is not slipping, the solenoid pack is stuck and not tell it to shift up. Could possibly be a TCM, but not as likely.

Tranny slips & wont shift past 2nd gear

Ok, you will need to first check the fluid level in this transmission. if the trans is sealed, you will need to take to the dealer for a fluid check. assuming that the fluid level is proper, this will usually be caused by a faulty transmission control module and faulty shift solenoids as well. these devices are located on and inside the trans and i recommend testing each device for flaws.

Most slips are the result of gear ware but, the solenoids and TCM will cuse this issue as well.

4l60e slips in 3rd and 4th

There are to many things that can cause this problem, best thing to is go get the ECM scanned for DTC codes at a transmission shop or Auto zone or Parts Source since they scan for free.
The ECM should have DTC code in it's memory on how the transmission is Performing and have the Transmission line tested for Fluid pressure.
Good luck and hope this helps. Oh and also ways check with more then on transmission shop if there tell you that you need a new Transmission,
It could be a simple as the transmission filter falling off causing the lost of transmission fluid pressure. Check the transmission fluid too.

1998 F250 2wd transmishion or rearend problem

Sounds like the transmission is starting to fail. If you get the jerky response when making a sharp left or right turn upon acceleration that is a sign that the clutch packs inside the auto tranny are slipping and grabbing intermittently. If the truck has pulled a trailer a lot in it's earlier days you can almost bet the tranny is the problem. Smell the tranny fluid to see if it smells burned. The burnt smell indicates slipping and excess heat.
