Hey Guys,
i recently picked up a 99 f150 with a 5.4 and the 4r70w. I am about to service the transmission and wanted to see if there was any up to date info on the jmod for the later transmissions. My reading tells me i have the best of everything and need only drill the separator plate and pull the lower spring from the 2-3 servo. any input welcomed, sorry for the lack of sc content but i didnt want to join another forum for a single need. The truck forums are lacking....
 
I think you will find that some of the holes have already been enlarged to the J-mod specs on the later model transmissions.

nickle, thanks for the link, i had already covered it.

Dan, i assumed as much as well. I have looked at the cvpi list as well were there is an unclear update by jerry for later trannies, i am thinking i am on track so i plan to press.

Thanks guys
 
The car valve bodies are much better than the ones that came in the trucks.

I wasnt aware of an update on the article from the CVPI site, the original article was written about 1999.
