Its the transfer case. It just needs to heat up a bit....Maybe? Mine does that as well, but I attribute it to the cold in Michigan.

Have you changed the tranny fluid lately? On my 2000, it shifted badly until I changed the fluid.

The transfer case should have little to do with transmission shifting. What lube did you put in the transmission? Some recommend Red Line MT-90. It sounds like the transmission lube is slow to warm up.

Agreed. I would make sure you have the right fluid in the tranny. Royal Purple seems to work pretty good. Also Amsoil...

Since you just had the clutch changed, try taking it back to the mechanic who changed it and ask him about the alignment for the shifter. the lubrication oil is probably just 90w gear oil and is the same weight that was in prior, so the oil is not it.

I would think that if it was something such as the alignment for the shifter, the problem wouldn't go away after 15 minutes. Just my 2 cents...

I have known several people with shifting issues in their manuals...they changed to Amsoil MTF 5w-30, and the problem went away.


Let me verify what I posted above. I don't want someone to put the wrong fluid in their tranny. I will update and verify asap.

That's pretty normal for cold mornings. You do want to verify that you have the correct fluid in it though. I can't remember if the 2001 had the AX-5 or the NV series - each require a different fluid.

Normal, I have a ford probe i use to drive in the winter and i would have to allow it 10 min to warm up so the fluid wasn't so thick and i could actually get it from N to 1 or 2nd. On really cold days it would sometimes take 15 min, best advise i can give you, park it in the garage if you have access, or allow it 10 min to warm up. so the fluid isnt so thick.

NV3550 is what is listed for 2001, 2.5L, and 5 speed.

Ok, I see two different transmissions listed on the Amsoil site. The folks I know used Amsoil MTF 5w-30 in their NV3550's with great success.

Amsoil also show's a EX NV3550 which they recommend MTG 75w-90 fluid.

I'm personally not sure of the difference in the two listings for the transmissions ?

Anybody..if not I will contact Amsoil and find out...

Ok, EX means except the NV3550. it seems they may have used a AX-5 behind the 2.5, so ya have to find out what tranny you have for sure.

Mine just started shifting pretty rough also now that it's getting cold. I changed the fluid to Royal Purple a couple of days ago based on reviews on this site and it works amazingly well. I doubted it would make a difference but it shifts much smoother and is much quieter. It even eliminated the roughness I had in neutral.

Yes but the mechanic could have not aligned the tranny, linkage, and/or transfer case which might make it difficult to shift.

It did not do it prior to replacing the clutch --did it?
