GaPrix Posted June 26, 2015 Report Posted June 26, 2015 I have a 94 GP 3100 4t60e. Is this model year trans able to use a 97 gasket, with the imbedded steel rather than just the cork? I'm guessing there was a slight design change in the trans gaskets? Quote
RobertISaar Posted June 26, 2015 Report Posted June 26, 2015 all 4T60/4T60E and 4T65 can use the same gasket, pans too even. I want to say the steel laminated ones came out earlier than 97, my 95 had one but the rubber was just flowing outwards and couldn't be reused. got a cork one, no problems for ~20K miles, then a slight leak, so I retorqued the pan bolts and it has been happy for ~35K miles afterwards.

RobertISaar Posted June 26, 2015 Report Posted June 26, 2015 hmm..... looking on rockauto now, a new dorman pan has a drain plug on it, but the interchange is only showing 4T60E applications... odd. Quote
GaPrix Posted June 26, 2015 Author Report Posted June 26, 2015 Okay, thanks. I wasnt sure as everywhere I looked it only listed the cork ones....edit a drain plug? thats interesting Quote
RobertISaar Posted June 26, 2015 Report Posted June 26, 2015 okay, so there are 2 different 4T60 pan/gasket designs, 1 4T60E and 1 4T65 that I can see. they're all just slightly different enough from each other to work on first glance, but probably cause issues in the future. I guess just stick with any 4T60E pan/gasket and you'll be okay. Quote
l67ss Posted June 26, 2015 Report Posted June 26, 2015 I have a 97 4t60 pan on a 2000 4t65..... Quote

Cough* Not to be pedantic here, but I know there is a difference between a 4T60 aka TH440 and a 4T60-E. I found this out with my '91 Euro way back. Ordered for the car, parts store says 4t60E, but had to go back a year or two to pull up a TH440 for correct pan gasket. That's all. Quote
Schurkey Posted June 27, 2015 Report Posted June 27, 2015 http://transmissiontechnologies.com/gm-transmission-pan-shapes.aspx 19 bolts on 440/4T60 pan 20 bolts on 4T60E pan Quote
pitzel Posted July 2, 2015 Report Posted July 2, 2015 Quick question here -- is the 4T60 and the 4T60-E filter interchangeable? I accidentially bought a 4T60-E filter and I have a 4T60. Quote
Schurkey Posted July 2, 2015 Report Posted July 2, 2015 First Guess: No. A part-number lookup might answer that question. Quote
