I used the search function, and some members have used this fluid with good results in various car automatics. My understanding is that this ATF meets Dex IIIG. The stuff appears to be pretty thick, almost as thick as a thirty grade A3 engine oil (HTHS=3.4!), and much thicker than Castrol IMV ATF, according to Castrol's not totally comparable PDS sheets for the two ATFs. I found some of the Transynd on CL for a dirt-cheap $8.00/gal. I am thinking that a few drain/fills on the old Imprezza might be a good idea. The old dear calls for Dex II. What does everyone think about using Transynd in our old Imprezza?
