What is your vehicle doing? Can you explain the symptoms in more detail?
Customer: replied 2 years ago.
It will drive fine for a while, then rpms go up but car doesnt seem to want to go, like transmission is not engaged or something.sometimes it feels like you ran over little speed sensors on side of hwy, but theres no bumps in road.mainly you step on gas and dont get the responce in take off like you should but rpms goes up

I have had to add transmission fluid every few months after having it a slow leak somewhere, the way I could tell it was getting low is it would start not acting right, then after I topped it off it would be fine for a few months
Customer: replied 2 years ago.
My mechanic drained fluid the other day and saw no metal filings, no code came up on computer...I replaced 1 speed sensor for transmission and he replaced other one for it is at place where it was rebuilt and they are checking it out.

Does the transmission go into limp in mode where it only has second and reverse gears?
Does reverse work normally?
Customer: replied 2 years ago.
reverse works, but a 4-6 months ago when I would start it up and try to engage reverse it would take a little bit b4 it worked but the last 3-4 months reversed has worked fine.if it goes in limp mode its usually just a little bit, if you turn off car and restart it, it might do ok for a little while.the longer you drive it the more chance of rpms going up w/ out car going like it should.

Its hard to get a mechanic to drive it around long enough for it to mess up.They just drive it a couple miles say everything seems fine keep an eye on it.Then you drive it for awhile and it starts acting wierd in the transmission.

Transmission shop just called said I needed new torque converter and solenoid pack, i told them I wanted a transmission cooler put on to, my cost will be 1200.
Customer: replied 2 years ago.
I dont know the codes, I tried to explain what its doing the best I can, but I dont have much more time now need to make decision.
Expert:  tims auto repair replied 2 years ago.
i wouldnt think it is the converter..though,i do think you may have a bad solenoid block,,
if it was the wouldnt even pull in reverse

4 or 5 months ago it wouldnt go into reverse when I first started up, it would have to wait a bit.Then usually if I added more fluid it worked better.Now reverse hasnt given me a problem for a few months.
Customer: replied 2 years ago.
Engine light is always on, replaced o2 sensors several times, heard it could be gas cap, maybe because the little flapper in gas hole is broke could be causing it, mechanic couldnt get it to go off.

if i were you,,i would try the solenoid block before pulling the transmission to replace the converter
