I feel like my trans might be built a bit. Truck lunges when I put it into drive, doesn't slip at all under full throttle when going into OD it locks up hard and shift firm through the gears. Took a pic of the torque convertor wanted to see if you guys thought that maybe it was an aftermarket piece. Thanks

 

from that pic, it looks like its a high possibilty its an aftermarket torque converter to me.

 

pretty sure it does not look stock

 

Wanna get either a programmer or injectors next, hoping that the trans is built up enough where il be ok for a while. Don't wanna go to crazy but just wanna have some more power and mpg. Thinking either rv275 or a smarty.

 

yup, looks like an after market.
and i'd go for a smarty
