It was either a Casull or a new tranny for the holiday so it looks like I will be looking into installing the NV3550 in late spring, early summer. I have never installed a transmission before. I have looked at the jeep tech pages on the 4500 and in some manuals. Supposedly the 3550 is easier than the 4500 on the install. Has anyone done one of these before? Anything big to look out for? I have 32's on it and am wondering if I will ever get 5th with this new trans. Thanks for any help!
The 3550 is what they use in the newer TJs, correct? I know they use a "HD" version of it in the Rubicon. as long as you're geared correctly 5th gear should be useable. Oh, and if anyone actually WANTS that old tranny you're replacing, they're probably crazy [img]images/graemlins/grin.gif[/img]
i dumped the peugeot for a 3550. AA has parts for the swap. they want around $2000 for tranny and parts. try to find a used one- i got mine from a 2000TJ that did a auto swap.
the 3550 bell fit the 4.2 and i used the 4.2 flywheel, clutch and pressure plate. you will need to buy the AA t-case shifter linkage around $56. also need to run a new clutch line to adapt to the 3550 external slave. i used the TJ slave.
beware of the new pilot bushing- mine pressed in flush with the crank. i removed the old needle bearing and attempted to remove what i thought was a pressed in donut bushing- was part of the crank. the new bushing is an oilite material- self lubricating.
you will gain a 4.01:1 first gear VS the 3.39 in the peugeot. the other gears are the same ratio except reverse was lower in the peugeot.
now you will have that boat anchor you always wanted.
