I recently picked up a Milano verde transaxle for my gtv6. The isostatic linkage is bent and trashed. Is it possible to use the regular gtv6 shift linkage? I assume not but figured I’d ask. Thanks
George,Appreciate all that Rob, I have 4 Spare transaxles and only one car. Don’t know how that happened but I guess I get carried away. One is an lsd out of a Milano which I plan to use. Two are out gtv6s both 1983 model years. And one I think is an alfetta box, but not entirely sure. How compatible are these boxes in terms of synchros etc? I belive the Milano Verde box Has longer gears and I think I’ve heard the alfetta box has shorter gears and the gtv6 is somewhere in the middle however I could be completely wrong. Also the internet is great and all but is there a good shop manual I can buy to walk me through the trans rebuild? Thanks for all the help again.
Joe,I'm in the same situation - I have a Verde transaxle that I want to put in my 84 GTV6 along with the 3L Verde engine I'm rebuilding.
@racingswim2006 - I believe you mentioned at one point that there is a particularly nice set of gear ratios that can be made for this swap, using parts from both original and Verde transaxles. Is that right? Can you elaborate?
Thanks for the advice Rob all good things to know. It’s about time I ordered myself a proper manual. I live in Cheshire Connecticut. I don’t think I’ll go crazy swapping ratios at least not yet. I have a 3.0 24v out of a 95 164Q that is destined for the car So at the least rebuilding the trans is a must.George,
You should have plenty o spares BUT you won't have another 1st gear "Milano" type dog ring if the other boxes are early V6 and Alfetta. You may choose to convert. There are tradeoffs for both.
Shop manual is a great resource for rebuilding these.
Gear ratios more generally are as follows:
Alfetta - shortest overall gear set. 1 overdrive gear. USA had all 4.10 final drive
81 GTV6 had unique gear set with only 1 overdrive gear. 4.10 final drive
82-83 had 2 overdrive gears. 3.42 final drive
84-85.5 same gears as 82-83. 4.10 final drive
86+ GTV6 and Milano had different gear set with much taller first and second gear, nearly same 3rd. 4th and 5th same. 4.10 final drive on all GTV6 and Milano EXCEPT Verde which had 3.54. LSD on Platinum (4.10) and Verde (3.54) only.
If you have a BIG press, lathe, mill you can get creative with mixing and matching some ratios. But it's limited. Splines are different on Alfetta and V6 for input shaft. 1/2 cluster on input shaft for any transaxle are native to the shaft. 3/4 presses off hard. 5th/R splines differently Alfetta vs V6.
Pinion shafts have different spacers and support for 5th. Different speedo drive. Different pinion bearings. And other.
A stock Verde transaxle is a fine upgrade for street use especially from an 83. Just swap over your input selector rod.
Where are you located? I may send you a PM. I'm in the midst of rebuilding several transaxles right now, have all my tools out.
There's a few "hybrid" setups that work well. The most straightforward "hybrid" version of this requires Alfetta donor gears and some machining. For your car, with a hot 3.0, a Verde trans is a fine street upgrade. Some people prefer the short 4.10 but having driven many configurations, I prefer the 3.54 Verde final drive for mixed use when coupled with a strong 3.0. These engines are not too peaky and pull the taller gear no problem. Does it leave some meat on the bone in certain situations? Sure. But it's a lot nicer in most situations.
