Well guys I fixed my clunking hard 1-2 shift on my 99 f150 5.4 by installing the transgo shift kit ($48). My truck was due for a fluid change anyway so this worked out great. Removed pan and removed accumulator body. Removed 1-2 valve and my spring came out in 4 pieces! Transgo gives you all the springs for all the gears, so even though the rest of my springs looked good, I replaced them anyway. My tranny is like brand new. I have the 4r100 btw, Mike

 

Pretty common for the springs to break with age and miles.

Good job on doing it yourself!

 

were you able to install the kit with the trans still in the vehicle?

 

Yes, you just have to drop the pan......easy ....Mike

 

thanks mike.
