I have to replace the turbo on my 2001 CTD with the Automatic Transmission. I have read that the Dodge used the HY35 on the 01-02 CTD with the Auto Transmission because it has a faster spool up rate which supports the brief speed increase during shifting in stop and go driving. I would like to know if it would have an adverse effect on my Transmission if I was to replace it with a HX35. The HX35 is easier to modify and has more capabilities of being modified. Any information would be greatly appreciated.
