I'd like to understand exactly what where the changes made to each model year.

Thanks

 

Here's my limited knowledge:


1999 - 2000
Color-keyed mirror backs
14mm lugs ('99 had 12mm)


2000 - 2001
Asthetic things - wheels, lights, grills
3.73 gear ('99-'00 had 3.55)
90 mm MAF ('99-'00 had 80mm)
Bilstein shocks
Stickier compound Eagle F1's


I'm sure I left some things off the list....

 

1999-2000

Also the overhead console was added to the 2000 and the tailight changed (position of the backup light clear spot). There were no engine changes in 2000!

Cheers,

...Dwight...

'99 had optional 6 disc, towing, and tonneau.
'00 made everything standard except optional tonneau. Added drivers side "oh sh*t" handle, overhead console, color keyed mirrors, 12mm to 14mm increase in wheel lug size, taillights changed from all red to clear center, added silver as an option.
'01 added 20HP to make it 380HP. Completely new lighting all around including the over bed brake light. Went from a 3:55 to a 3:73 rearend, improved intercooler, enlarged the airsupply from the fenderwell, signal mirrors(I think), "oh sh*t" handle above passenger side, different wheel designs, different lower crank pulley design.

Front end "clunk" standard for all years with optional leaky intercoolers for the '99 and '00 years...so far.

I think that covers most...

I'm sure that I must have fogotten something.

 

...The sun visors for 99 and 2000, were standard single ones with non lighted mirrors.
The visors for 2001 are lit and they have a second visor that folds down when the main one is to the side...

Heh heh, had to throw that in there....

 

No, the '99 and '00s had 360hp stock. There were no power changes until 2001 (380hp).

BIGGEST difference between my 99 and the 01. The 2001's monthly payment is $22.00 less! Now that progress!!!

 

One thing FlashSVT and I found this weekend is that the '01 have an additional 4-prong connector on the tow-hitch electrical connector that my '00 doesn't have.

From a strictly Transmission point of veiw, hte 99s have a differnt Solenoid, (in 00 they added another filter, I think), the 2000s and teh second Model (2001.5) are almost identical except the clutch plates in the intermediate clutch are a differnt material, the original 2001s had the mechanical diode on teh direct clutch, but they switched back to a Sprag assembly half way thru the model year and the 2002 is the same as the 2001.5. Also, all three years have different EEC software, so a chip from any given year will not work on any other year to the best of my knowledge, a tuner may tell me that's wrong, but it's what I've been told.

What about the drive shaft's on the 01's. Is it aluminum?

 

Good call, insanedaddy, the new trucks have the aluminum driveshaft.
