Trasmission swap question
« on: May 11, 2010, 10:10:19 AM »
I have a 94 8V tracker with a loud transmission in 3rd gear.  Rather then pay for a rebuild I am going to do a junkyard swap.  Can I use either a automatic or manual transmission interchangeably, meaning straight swap, or are there some other things as well like transmission cooler etc.?  I have a five speed manual right now, but I am flexable due to budget issues.

it will bolt right up. but if your going from 5 speed to auto you will half to change the fly wheel so  the torque converter will have something  to bolt up to. and yes you would need the radiator with the hook ups for the auto trans lines and the wire connectors are different for the stater and back up lights there is 2 wire connectors that go to the trans one for the 4x4 and one for the reverse lights and starter. and also the petal assembly  and shifter mounting and cables. if it was me i would try and find another 5 speed because its quite a bit of work. it is much easer to go from a auto to a 5 speed a lot less stuff for the 5 speed. hope this helps

Also, a manual trannied 8V doesn't have the vacuum port on the intake for the the tranny vacuum modulator hookup.  So you will need to drill and tap the intake manifold and add the connection.
For the cooler you could either just loop the line and not run it through a cooler or add an aftermarket cooler and not use one that is built into the auto radiator.
Then you have your whole pedal situation to deal with....3 pedals vs. 2, clutch switch vs. brake interlock, etc.
I am pretty sure there are some wiring differences too....nothing that you couldn't get around, but it would involve cutting and splicing wires.
As mentioned, I would just swap in another manual tranny, if it were me.

There very easy to rebuild.  A hot plate, some oil, dead blow, and a small press will get ya through it.

Thanks for all the answers, sounds like it is going to be a straight swap then. Should do the clutch too while it's apart.

If you are putting in an auto (which it sounded like was your intent, reading your original post), you won't use a clutch.
If you are going to put a manual back in, and if the old clutch looks ok, I would run it and not put in a new one.  Although putting in a new pilot bearing might be a good idea....they seem to wear out faster than the actual clutch does.

I have just been doing a swap from manual to 3spd auto. It's not that hard but it is a bit of mucking around and you need all the right bits.

You swap the flywheel for a flexplate. Make sure you get the bolts and flanges that go with it. 

Just add a decent sized afterarket tranny cooler. I have swapped the pedal box but you can keep the manual one and just remove the clutch pedal.

The console is different around the shifter too so you need that and its mounting bracket. Where the shifter mounts to the tunnel is also a bit different but that's no big deal. You also need to wire in the shifter light.

just make sure that you get the kick down cable with the auto.

Sorry, should have clarified, looks like I will be doing a straight swap with another manual.  I would rebuild this one but I live in a apartment.
