usually the auto trans has a filter in the pan. if the filters clogged it cant get enough pressure to shift. i recommend a new filter and gasket. cork gaskets are way easier to install than rubber gaskets. coat the cork gasket with form-a- gasket, you dont have to use an extreme amount, just enough so the gasket sticks to the pan.

You might have a bad throttle position sensor that's going bad.You didn't say if you had a check engine light that's on or not.If there is then I would recommend that you have your local auto parts store retrieve the codes and and that will give you a better idea as to what the problem could be.Without actually being able to completely inspect all the necessary systems I would only be making a guess according the information that you provided to me.It sounds like a bad throttle position sensor

I recently changed my transmission filter and fluid. I added lucas transmission stop leak. Now lt dont go when I put in gear.

I would say either the fluid level is too low, or the filter is not properly seated into the valve body and not getting fluid into the pump.

2006 dodge grand caravan transmission fluid low but cannot find a leak

check your rear main seal. Also try changing your trans fluid, trans filter, and your transmission pan seal. I recommend you put lucas transmission oil in it and a quart of the Lucas Stop Slip and leak sealer

What cause my 1995 buick regal to jerk at 55 just before passing gear,i do have a leak in front tranmission line would that be it

Stop any oil leaks as the transmission requires exacting oil pressure to do the job. Any leaks reduces the pressure so gear changing is affected. Besides when do you know if the oil level has dropped below operating level and will be insufficient for the gear box.

Transmission is leaking but still shifting?

any product that says stop leak or stop slip is a patch (if it works at all)
Sadly, you will have to have her rebuilt.
you should have a 4L60E transmission in there (v-6)
If you plan to get a salvage trans, make sure you get the right one as they changed over from OBD1 to OBD2 that year.
The Blazers ran both series (1&2) and you must put the right one back in.

I am seeing a small amount of transmission fluid under my 2003 jeep liberty. what could be causing this?

A loose drain plug in the transmission pan, a loose bolt in the pan, a bad gasket. It could be coming from the power steering as well. Check the resevoir and hoses.

2005 dodge caravan, leaking power steering fluid(rack n pinion), i am using lucas power steering stop leak. How long can i go with(lucas) before i replace the rack? fluid is not leaking anymore...

I really wouldn't push it more than 3 months or especially if climate change once the leak stop has stopped the leak it doesn't like temp change. but i've done radiator stop leak from Lucas and went 6 months before the leak appeared again. good luck

My 1993 Geo Tracker auto tran jerks when starting off from a complete stop,it's as if it's completely out of gear and drops back in when the RPMs come up? It works perfectly after that.

Check the fluid level to make sure it's full. If it is the problem is probably internal and will require a rebuild. This is one of the first signes of transmission or torque converter failure.
