ok here is the deal, get in car put it in drive accelerate and i get a bit of a "dead" zone on the trans then it will engauge 1st and then if i get it mid to heavy acceleration it will shudder hard.
If i get into car and shift to 1st i can do whatever i want with the trottle hard light mid acceleration and have no slip or shudder and a nice shift thru the rest of the gears. any idea what this is, i had someone say it may be the Torque converter.
i have another trans that i am currently rebuilding but would like to get this one into working condition for another project or to safely sell it without concerns of a baseball bat to my knee caps
 


get it scanned... i bet u have p1811, max adapt long shift. usually caused by bad pressure control solenoid.
 
the tranny is supposed to be less than 80k driven by an older couple, but i hear that story too often to be 100% on that, but its not a clutch slip and considering 1st locks i doubt its clutches. How do i scan the trans, i have a dhp tuner/scanner but i have never seen a trans code tripped so do i need to find a dealer?

I did notice that if i put the trans in 1st i hear a bit of a noise, it doesnt sound like anything bad just a slight tone change, if its in any other gear i dont hear the tone change.
 
I took my car to a transmission shop here locally. They dropped the pan, changed out fluid, put new filter and o-ring in, and scanned it for problems for $100 bucks. I'd take it to a transmission shop before you take it to a dealer. I agree though with the comment above sounds like a pressure/shift solenoid. Especially when you put it in 1st and bypass it shifting automatically.

Everyone dogs these transmissions but I was reading a post on here I believe last night. The guy said 274k on his original tranny, beat on 20-30 times daily, 50 track runs, and still shifts like butter. I have 84,000 miles on my original and I'm kind of the same way. I usually put the car in boost everytime I take off :th_laugh-lol3:. I don't go launching all hard though, usually just rolling into the throttle. Guess it depends on how you take care of it. Scan it, replace faulty electrical part, fixed.:th_thumbsup-wink:
 
This sounds a lot like what is going on with my montana trans. I'm thinking pressure control s. Although wish that particular gadget was not so difficult to get to and change..

It does not happen freequently enough for me to test if it does not happen when shifting manually though. Last time I had it scanned for codes it didn't throw any but don't know if the regular engine scanner grabs trans codes as well.
