Hi guys i have a 96 ford bronco. i had the 8.8 rear end pulled out and had a 9 inch put in. after all the work was done i noticed that it was shifting hard and i had no speedometer and no overdrive. the mechanics that did the work said that it was a speedometer sensor that would not clip into the 9 inch and that i would have to take it to a dealor to see what they could do. can somebody please help me i have spent to much money already and realy dont want to spend alot more just to go muddin. your help would be greatly appreciated
I'm sure someone will be along soon. I have an answer but not sure I am correct. If I am, others are more tactful than me and can break it to you more gently.

I believe your VSS was in the rear 8.8 diff (tone ring on the gear)....which your computer uses for a signal for the speedo and the tranny.....

First off, welcome to FTE and the Big Bronco Forum. I only wish that you had posted this quandary BEFORE doing the swap. We would have issued the following warning...
Without the VSS your transmission won't ever shift properly, your speedometer will never function properly and your cruise control will never work. I know the E4OD has no provision for putting a VSS in it so moving it up to the transmission isn't an option. I am not certain about the newer auto that some 96's got. There may be an aftermarket kit to put a VSS inline somewhere but I couldn't tell you who makes it. Either way, you have to find a way to keep the VSS or risk destroying the transmission and never knowing how fast you are going. The ECM simply won't control shift functions and everything else that relies on VSS signal without this sensor. Your ABS won't work in the rear either and may end up eventually affecting the front braking as well as the ABS computer also uses the VSS to determine wheel slip in the rear axle and without ANY signal it goes into fail-safe mode. You would be better off finding a D60 with a VSS provision or staying with the 8.8.

I think GreyStreak meant he would have been better off with the 10.25 and a D60 front end if he wanted to upgrade his axles, so that 1. he could have kept the VSS for speedo and trans shifting, and 2. would have been an upgrade. The other option would have been to modify the 8.8 for better axle bearings that didnt wear on the axles. If he truely wants to keep the 9 in, either make a VSS for the 9 inch, or move the VSS up to the 87-91 postion on the transfer case output shaft.

92 to 96/97 had a combined VSS/ABS sensor in the rear axle. 87 to 91 Fords used a VSS in line with the speedo cable on the output shaft of the transfer case, or in the case of 2wd's on the output shaft of the transmission. It was often considered just a VSS for the cruise only but it was also used by the computer as a VSS. It doesnt have a tone ring but uses a speedo gear with revelotions to determine vehicle speed. 87 to 91's sensor in the rear axle was for the ABS only. I am sorry to say but like greystreak said your first mistake was swapping an axle in that wouldnt support the VSS module that you need for your transmission.

ok thank you guys so much for your help. i checked up on some of the stuff that H2OnO2 posted and i think that i am going to invest on a relocator at the transfer case. it seems pretty simple and not to expensive. again thank you all so much. i appreciate it very much.
If you go thru with it please get back to this thread and post results/pics, no doubt others are facing the same issue and your experience could help!

Dana 60's were not very common, if at all, as rear axles for 3/4 to 1 ton trucks mid 80's onward. Very common as front axles for 1 tons from late 70s on though. If it was present as the rear end I think the VSS was moved to the transfer case.
