Help NEEDED! 4L60E or 4L65E? Which filter?
I am in the process of pulling out the radiator and putting in a Racing all aluminium item from Dewwitt and would like to change all fluids and the harmonic balancer while i am at it. Here comes my question. I am absolutely clueless if my transmission is a 4L60E or 4L65E. When i LOOK at the transmission pan it's got a swirl pot bulging out at the bottom and was told its a 4L65E cos of that.
I got AC Delco Dexron 6 (13 Litres due to the bigger radiator). And am in the process of ordering a Transmission kit. Surprise surprise, the supplier told me i cannot supply you the kit because your model is one of those "ambiguous models" that had a filter for that specific year and model only!!!!
So here come the questions:
- I am really not sure what filter to order. AC Delco says that my VIN (with a U in it) got this special filter
- I am also unsure if its a 4L60E or 4L65E since i wish to buy n replace the shift solenoids and i need to know which tranny i got.
I went for this radiator cos the old one started leaking and scared the s&&t out of me as I'm now thinking that the fluids might have mixed.
Your help is really appreciated. I know that this might be a silly question but i am still a beginner when it comes to these fabulous machines.

- It seems like all C6's came with 4L65-E (as per GM quotation)
- the 05 had a specific transmission only for this build year and was changed in later years why?
- The RPO code M32 indicates that its an Electronic Auto transmission. M32 was said to indicate the presence of 4L65-E while an M30 would indicate a 4l60-E but am not sure if this is correct.
how does one to tell what transmission is in there? Is there any way to recognise the 4L65-E or is there some number i could find on it?
More confusion !!
