HELP - Difference in TPS...auto vs. man

[BimmerBall]

anyone know the difference between the two? does it really matter which one is used? the manual is about half the price of the auto. thx



EDIT: N/M. Looks like the expensive auto one may be for the models with the selectable transmission modes.

I think the expensive one is for other than the standard auto tranny. The one that I pulled off of my track rat (which started life as an auto) was the same part as cheaper of the two TPS's that replaced it.

yeah, that's about what i came up with. the standard auto/manual look like they share the same tps (square connector) but the selectable mode auto trannies look to have a round connector. i.e. the selectable mode auto's have a special tps.

no difference unless you have the 4HP-22 EH transmission, which uses a 6 pin variable TPS switch. 99% chance you don't have one of these either :p
