Transmission and/or handwritng analysis sleuths needed...

[jimf909]

Hello,

I need help with handwriting analysis and/or transmission sleuthing.

Transmission: Vanagon 2WD manual 4 speed

Data: With 27" tires (Nokian WRC3 215/65 R16) in the stock .85 fourth gear (confirmed last year during a rebuild) the van goes 75 mph at 4,488 rpm. Doing the math shows this is a 5.5 (5.43?)ring & pinion (it would run 3,951 rpm at 75 mph with the 4.83 ring and pinion)

So this van has a non-stock 5.5 ring and pinion (not confirmed during last year's rebuild...more on that later). That's fine. I like the high revs with my Bostig and slightly oversize tires.

Mystery: In 2005 the PO had the trans rebuilt at AA Transaxle. What's the $500 item under the red arrow that looks like "LAB 500"??? Could this be a charge for the 5.5 R&P? What do you think LAB means?

Looking forward to tips, clues and ridiculously obvious answers.

There is lot of bad advice here.

The clutch rings are held in my things called dogs, and here they clearly got one from a


Lab.

If you look at that receipt it shows a DU tranny code which is early WBX, so your van being a 90 isn't relevant to that tranny or what might be inside anymore.

I believe stock is 4.86 ring and pinion in the WBX 2wd. I have a calculator on my PC and using your info this is what I calculates with your tire and stock WBX gearing.


Engine speeds in top gear:-
30 MPH = 1546 RPM 40 MPH = 2062 RPM 50 MPH = 2577 RPM 60 MPH = 3093 RPM 70 MPH = 3608 RPM 80 MPH = 4123 RPM 90 MPH = 4639 RPM 100 MPH = 5154 RPM

More helpful info.

Interesting on the DU code. Ive got a prettty decent set of paperwork going back two owners to 1994 but nothing other than tranny seals and clutches in all of it. The PO was pretty hands on and swapping out a trans at one point wouldn't be out of the question but his paperwork was also very detailed.

Thanks for the math, Mark. That's pretty much what I have too so we know for sure it's a 5.xx ring and pinion.

The tranny is being rebuilt by Ken at German Transaxle so we'll know all the details next week.

This exercise is an attempt to discover when the ring and pinion or entire trans was changed from stock and that may forever be a mystery.

Thanks, everyone.

Nokian specs says the 215/65R16 WRC3 turns 770 revs/mile

---------------------------

So if 5.5 r&p and .85 4th gear we get:

60 mph = 1 mile/minute
60 mph = 770 tire revs/minute
770 x 5.5 x .85 = 3600 engine rpm

75 mph = 1.25 mile/minute
75 mph = 963 tire revs/minute
963 x 5.5 x .85 = 4500 engine rpm

------------------------------

If it was a stock DU code inside with
4.86 and .85 we get:

60 mph = 1 mile/minute
60 mph = 770 tire rev/mile
770 x 4.86 x .85 = 3180 engine rpm

75 mph = 1.25 mile/minute
75 mph = 963 tire rev/minute
963 x 4.86 x .85 = 3980 engine rpm

-------------------------------------------------------

Looking at Vanagon Green Bentley page 2
US spec 1.9 engine used tranny codes DU and ABD
US spec 2.1 engine used tranny codes ABD and ACW

roughly put,
83-84 used DU
85-86 used ABD
87-91 used ACW

The actual teeth counts of the various gears of the 3 tranny codes for 2wd wbx 4 speeds are given separately on various pages.
All 3 are shown together on page 35.32
