just talked to tec at transtar main difference between transmissions would be gearing

There is no difference. I ran a none Turbo Transmission in a Turbo PT and I also used the core from a none Turbo to completely rebuild the transmission. There is no internal differences.

I am not sure why you were told they were different?
I have a very rare complete Chrysler factory Service manual and all the up dates ever done to the PT Cruiser A604/41TE. The gear packs are the same.

Actually there is a difference in gearing depending on the year.

It appears that 01-04 indicated "2.7 overall top gear ratio" while 05 and up indicated "2.6 overall top gear ratio". I have checked the VINs of many cars at my junkyards, since they post the VINs on the website, and those have been my findings. Turbo or not, the pattern holds.

Thanks I found the same thing
41le parts are interchangeable also
Gears (differential) would be different

Yep, other changes came in 2007 with variable line pressure. Other changes came in 2009. And even amoung the 2007-2008 models, the parts numbers are different for the turbo tranny compared to the N/A.

Also, 2001/2002 PT Cruiser got the A604/41TE. Starting in 2003, N/A's usually came with the 40TE and mostly the turbo models got the 41TE. The only real different in these are the number of clutches in the packs.

Overall, the confusion usually comes from compatibility. In most cases, the auto tranny from a 2001 thru 2006 PT are physically interchangeable no matter the model. The differences are minor and inside the tranny. They mostly have to do with durability and gear ratio. As a rule of thumb for the A604 in general, newer is better since Chrysler made almost continuous changes trying to make this bad transmission design better. And they eventually did. By the era of the PT Cruiser, they were not too bad. And from 2003 forward, there are not near as many reports of failed tranny's in PT's.

If you have a 2003-2006 GT, find a tranny from a another turbo PT. It doesn't need to be a GT but should be a turbo. An N/A from this period with have the 40TE with a lighter clutch pack. If 2007 or newer, you will likely need to match the part number on the sticker on the top of the tranny to get the right one.

I would like to see and read where this info came from..
And please show me the MOPAR/CHRYSLER parts numbers of the gear packs supporting the gear ratio info and not a sales advertisement about specifications. LOL!

[myckee]

Sure, I can post my info regarding the top gear ratio.

As far as part numbers, if you are so interested, I allow you to go look them up yourself. LOL!

LOL ok but see you did not read what I requested?

These are NOT the parts numbers of the gear packs specifically indicating different ratios only a specification informational . LOL

Look what ever............. I don't really care anymore... arguing things on this forum seems just a waste of my time anymore ... good luck finding the real part numbers that I asked for to support empirical information!

I know few of you still want to find fault with my responses....LOL

[myckee]

Oh yes, I certainly did read it well. You said you wanted to see and read my info. So I posted it directly from Chrysler. You have seen and read now presumably.

But maybe not because I told you that I allowed you to go look up the corresponding part numbers yourself. Lol

But whatever, I know you cannot accept being wrong. Lol for me it is a great source of entertainment. LOL
