Ok, I have delt with a lot of underdrive pulleys in the past and most of the time I have to end up getting new belts that are hard to find. Does the ASP pulley use the same size belt or are the new smaller belts easy to find?
Also for my next question. The 3.89 gears go where? In the tranny or is it the timming chain gears? So if I was to get the 3.89 gears would a TCM from a 2.7L work fine in a 3.2L motor? If so I know where I can get one for peanuts. Also the 2.89 ghears come from a SE and a 300m right?
Keep the stock pulley and install the 3.89 gear. With the underdrive pulley you will see nothing on performance. You think is more easy. Hope for you that the stock pulley isn't stuck on the crank shaft.
The 3.89 gear will give you better performance. Instantly you will see the difference. It took 2.5 hour to change the gear. If you look at the end of the tranny ( near the tranny mount) you will see a cover. You need to remove this cover to change the 2 sprockets and chain.
The how to for the 1st gen were what I went on.
Its pretty simple, just remove the diff housing, and pop the 2 sprockets and chain out, and put the new ones in. Forget what other things I had to take out/loosen, but the how to page decribes it pretty well. :p
There is the how-to probably here somewhere and on the 300mclub board but basically you need to raise the front end on jack stands/using custom ramps or 'other' .
Then remove a cross member as well as lifting and lowering the transmission, through the process it only has to go up and down a couple of inches or so both ways, at various times as you work then remove the cover after letting the fluid drain-out.
Then you remove the gears and chain all at once then swap in the new gears put them in the chain and put back as one.
I got as far as removing the gear's retaining clips and could not get the gears to come out as they are supposed to but I had the parking brake on and didn't think that was the reason because the how-to never mentioned it.
I was later told that might have been the problem, after I just gave up and put it all back, so I'm wary of giving it another go in the spring, but since I have them I will probably do so just need some time for the memories of agony to fade.
If you can't find the how-to PM me I have PDF version of the how-to somewhere and I'll dig it up.
EDIT: I can't spell.
