I did the Isuzu to getrag swap. I know the ppm for the speed sensors are differnt but cant find a definitive answer to what the getrag ppm is.

I need to find out so I can change it in hpt so my speedometer is correct.

Thanks for help.

I have been unaware of anyone who had to do this. All of the threads and guys who have done this swap have not mentioned a word about it. I'm guessing everyone used the getrag VSS, deleted auto codes from the pcm, and it adapted properly.

None the less, I know a guy named Philly D (check the transmission forum, I believe he has a 3page thread there) did the Isuzu to getrag. Shoot him a message, see what he says. Most everyone else did an auto to manual swap (Lenko, Alex Richards [thread in photos and media section])

Most people I've messaged that has done the getrag swap has either gone from auto to the manual or also done an Eco swap at the same time.

I guess to confirm this I just need to find someone with a f23 getrag and hpt and have them look up what the vss ppm is.

I've done both... auto to getrag (on the 'vert in my sig) and the isuzu to getrag (on my old DD, green 98 Z24). Both isuzu and getrag are 4000 ppm. My speedo was never affected.

Thanks Lenko for the clarification.
Now I just need to find a plug for the vss and Ill be back in business.
