Quick question.
I have an 05 Expy (4R75E trans) that I’m about to replace the torque converter in. There are basically 2 available locally; a ‘high stall’ and a ‘low stall’. Best I can find the ‘low stall’ is somewhere in the 1700-1900rpm range and the ‘high stall’ is more like 1900-2100. Just a quick stall test (stop the brake and gas it) seems to indicate I probably have about a 2000rpm stall speed now (high stall). I’d rather put in the ‘low stall’ version as I HATE a sloppy feeling TC (I find the stock one to be a bit more ‘loose’ than I like) however, I’m a bit concerned that the turbine sensor on this tranny will not ‘see’ the stall speeds it expects and throw it into a limp mode. Anyone have any experience with this? I know the safe bet is to just stay stock but like I said, I prefer a ‘tighter’ feeling TC (actually I prefer a good old fashioned clutch but that’s another discussion). I hoping to do the job this weekend so I need to get my info together quick.
Thanks.
