So I picked up a tcase for my 97 5.9 1500 as mine was broken did not notice at the time that on mine there is a plug-in on the tail housing of it that the new one I got doesn't have does anyone know if this will be a problem thanks

 

nobody has had this happen can i just change the tailshaft housings on them

 

Yes, that's going to be a problem, and it's only the first one. Apparently, your replacement t-case is from a 98 or newer truck. So, no provision for the VSS on the t-case tail housing. The second problem is going to be that the shift pattern on the newer t-case is also different.

If your original t-case is still in one piece, you could conceivably mix and match parts to get a t-case that will work. Otherwise, it's going to be difficult to get your truck to be friendly with the newer case. Biggest problem is going to be that VSS.... Which provides vehicle speed information to the PCM. Without it, no speedo, no cruise control, no abs...... and possibly no air bags either.

 

So is it as easy as just switching out the tail shaft housing from mine to the new one or is there internal stuff that has to be changed too

 

I suspect you will need the rear output shaft as well, I don't know if the newer ones had the provision for the VSS drive gear.

 

when i open it up then they should be vissably different then

 

The tailshaft on the old case will have the drive gear for the VSS. The tailshaft on the new case may or may not have the splines that gear goes on. If it does, the job just go a lot easier..... Still need to remember the shift pattern is going to be different.

 

ok so i would just swap those parts over then to the new one and shift patter isnt a problem i have the linkage and lever for the new one too

 

Bear in mind the shifters mount differently as well. The older ones mounted to the trans, the newer ones mount to the body.

 

yup know that so if there isnt the gear for the vss on the nw one i have to pull the whole case apart then to switch the shafts out correct
