2wd/4wd

Will the 2WD 4.3 W series engine line up to the 4WD 4.3 W series transfer and transmission without some extreme degree of difficulty?

AFAIK, the engiens are identical. The mounts attached to the engine are considerably different, but the engines are the same. If you're performing a swap, make sure the years are the same between the donor/receiver, or you may have some other connection issues. You NEED to use the PCM from the AWD chassis for an AWD vehicle, so mixing them is not an option.

Yes, it is a swap. The donor motor is 2WD 95, the receiver is a 4WD 94. As near as I can tell without actually doing it, the connections are the same also. The engine mounts I assume are interchangeable. This appears to be the only reasonable priced solution, as any 4WD motor runs about 3 times the price here. Thanks for your help. Any other suggestions from anybody?

I did that exact swap last summer- but both were 2wd- the only problem- was--- the egr valve is different- must use the one from the 94- the 95 has the connector at 90 degree and plug is different- also there may be a crank sensor in the timing cover of the 95- but just don't use it- other than that it is plug and play!!! I got a great deal- found the 95 for $500 with only 87,000 miles!!! my 94 had 318,000 when it spun the rod bearings...

Only 318,000? I wonder what went wrong. Should have lasted a half-mill or more. Must have been defective. Too bad you didn't have a Honda. It might have lasted longer (on about the second replacement engine, sixth transmission, and new wire harness). ;)

It was fine- wife was pulling a stock trailer- with no tachometer- she accidently was in second gear at 70 mph- instead of 3rd- talking to her girlfriends- didn't realize it- poor engine ran its heart out- never did burn much oil- heads were original-never had an engine problem till then- did change trannys at 242,000- a $350 salvage yard- plugged right in as well---I was trying to get to 500k- the only other I'd heard of went 330k- but now with the '95 motor- I have reset the clock- look to go a lot longer......

Why do I suspect there was just a bit of "discussion" about that incident? ;)

She had waited a couple days and asked me "what if" it was in 2nd gear instead of 3rd- I had to meet her with the Dually to pull the trailer home- while the flatbed got the van- she sat along the interstate for 2 hrs- with her niece and nieces, 2 and 4 yr olds- so she learned her lesson- only 90 degrees out- engine was seized- then it actually started once it coolled down- but boy did it knock- my mechanic buddy wanted me to rebuild it- or buy rebuit- nearly $2500- I used the internet salvage yard search- found the engine only 45 miles away- the day it went online- called them- they pulled it on a wednesday- I got it on thurs- was driving the van- pulling the trailer on Sunday night- now has noticeable increase in power- sometimes you win once in a while......

HAA! LOL :D

Not laughing at your pain/trouble, but that's a good story!
