So my trans is a 1996 46 re. I have available a 92 46 rh (?) available in unknown condition. I'm running the 96 EFI and computer, can the hydraulic OD be converted to the electric, or will the 96 computer not have a problem with the older trans? I can pick the hydraulic OD up cheap, then have it rebuilt and waiting.

To clarify my sluggish stop light acceleration, back before the fluid dump, I could fry the tire (open rear) leaving a dead stop. Now it won't spin at all, but moves the truck well after the first 10' or so. Both the acceleration issue and the loss of OD both were noticed after the fluid dump, the stop light thing right off. Dropping the trans pan is a $145+ for material only experience these days, if it would help, I'd do it, but if it won't help I'd rather put that money towards the rebuild.

I’ve had my 2001 trans in and out 5 times, left an o-ring out the first time for the lock up, burnt the front clutch out. The trans is more complicated than the reg 727 mainly in the VB and OD. The clearances in the OD have to be spot on and measuring that takes special tools (made mine) the OD also takes a big press to service the spring and clutches, once out replace spragg and Torrington bearings. I can do one now real good but it was a learning experience (I could do the 727 blind folded) best leave it to someone you KNOW is good with these trans.

The short answer is no, the 96 PCM will not work the 92 trans. Maybe someone has done it with a flash program but I would have no idea how. The O/D and L/U work the same on the RE as the RH but the RE has no hydraulic governor and the RH does.

cudaman and geetar are correct. i guess it depends on how comfortable a guy is tearing into these things, plus having the necessary tools to do so. which i completely forgot to mention ! spank
i guess in Gene's case, it would probably be best to have someone who knows the ins and outs of these transmissions, do the job.
it's too bad you aren't [lots] closer. there is a guy down by the Pittsburgh airport that is VERY good with these transmissions.

They really aren't that complicated. The 727 is probably the simplest auto trans there is, part of what makes them so reliable. The 518 is basically the same with a compounder added to the back of it. If you have a press with a little ingenuity and fabrication you can get the O/D portion apart. I once used a floor jack and my steel work bench to get one apart. It looked pretty sketchy but it worked. Of course the tools are available and probably don't cost that much.

Well, the last 727 I rebuilt was back around 1990. Someone else is going to rebuild the trans for me. Its $1200 at the local guy, if I carry it in and carry it back out, and he was backed up at least 6 weeks a few months ago. I can get a remanufactured trans from a national chain for $1500, dropped off at my door in about a week, that has a 3 year warranty (the local guy has 1 year). Still not looking forward to pulling this pig out (its a 4x4 truck), sure hope my buddy gets his hoist up and running by the time I need it.
