Just changed out transmission on my 98 ram 1500 2wd now all it does is die when I put it in any gear it starts right back up and no codes any help with this would be very appreciated

 

Did you have the crank position sensor out of the way when you were doing the R&R on the trans? If it was still bolted to the motor, you likely damaged it.

 

I agree with @HeyYou . About half a year ago I swapped in a freshly remanned 47re from these guys, https://reman-transmission.com/trans...des/?code=47RE, and had a time with it after it was installed. Naturally, I thought it was a problem with the transmission and even called in to reman wanting a refund but after taking it to a different transmission shop they told me whoever installed it damaged my crank sensor. Not a bad fix but had a time trying to figure out what was wrong

 

Worth checking the crank sensor but sounds like it's something else. What year trans did you put in and where did it come from?

 

not sure in what way its dying if it lurches and stalls I would suspect the torque converter is locked up or something similar inside the trans, as I say this I would a assume its and automatic but is it a manual by chance?

Next I'm with moparite, verify the year the trans is for, it seems like you cant stray more then a year or so away from your model year and have everything work correctly, have you tried giving the truck every so lightly on the throttle when shifting, I had a bad IAC and it would stall when shifting into gear, like I said LIGHTLY on the throttle, just enough that the pedal is controlling airflow not the IAC motor.
