face=Arial>From looking at Service Without Guesswork, it looks like there is a
<BR>significant difference in the final drive ratios, but it's hard to
<BR>predict exactly what you'll find, because the ratios varied somewhat
<BR>by year. It might be possible for you to disassemble both and <BR>exchange
the innards to get the correct ratio for your Type 3. The <BR>Type 4 got
higher ratios, I assume because it had a bigger engine.<BR><BR>The Type 4 AT
also has 2 central mount points at the top, sort of <BR>like "ears" at 10 and
2, from which the engine/tranny was suspended. <BR>Those may be in the way if
you try to install it in a Type 3, or you <BR>might be able to cut them
off.<BR><BR>There's got to be lots of Type 3 ATs out there in boneyards in the
<BR>southwest, but I realize you've been looking hard and coming up

<DIV>Well, checking some of the info I got from Russ, says that there were 2
different sets of AT final drive gear ratios. A 411 (sedan) got the same
3.67:1 that the type 3 got. The 461 (wagon) got the 3.91:1 final drive ratio.
The 411 is marked ED, while the 461 is marked EC (how you tell the difference
between the 2). </DIV>
<DIV>I think the "ears" will clear though. If not, you'll have to cut them off
like Jim suggested.</DIV>
<DIV>But, the type 4 uses larger CV joints than a type 3, so you'll have to
swap the CV drive plates on the trans for a set of T-3 drive plates, or swap
the drive axles and outer stub axles for t-4 parts.</DIV>
<DIV> </DIV>
<DIV>I do agree with Jim, that you should be able to find a good type 3
trans in your area. Are you looking for a 003 300 035 A (used from 8-1968
to 8-1971 (like your car originally had?)) or are you looking for a 003 300
035 H (used from 8- 1971 on )? </DIV>
<DIV>I'd look into using a late model torque convertor IF you're really
worried about "overheating" the trans. Look for part number 003 323 571 D, as
that convertor was used in both t-3s and t-4s with a "trailer package". This
IS the convertor that Jim recommends. It'll have a D stamped on 1 of the
torque convertor mounting lugs. It was available for ALL 003 AT transmissions
(t-3 & t-4) except those used in a bus. :O</DIV>
<DIV>I hope this helps.
