Guy i got it from said he'd do the swap if I got the parts but all he said was to get the input shaft and the drum its connected too. ]]> Dan18 https://blazerforum.com/forum/engine-transmission-35/input-shaft-swap-107691/ https://blazerforum.com/forum/engine-transmission-35/column-shift-park-but-dash-shows-reverse-107685/ Fri, 10 Apr 2026 00:29:20 GMT 2001 Blazer 4.3 engine 4X4.

I can get all gears including park but the display on the dash indicates reverse when the transmission is physically in park and will not let me start the truck unless I put it in neutral. Any help would be greatly appreciated.

Cheers!

Recently, occasionally when starting my 2022 Blazer RS the RPM?s max out for a quick second. It appears to coincide with the gauge needle moving from 0 to max and return to normal RPM?s. Is this the start of a problem? Can this be diagnosed at a dealership if it doesnt?t happen when they start the vehicle? ]]> Steveben https://blazerforum.com/forum/engine-transmission-35/rpm-max-start-107674/ https://blazerforum.com/forum/engine-transmission-35/car-spits-starts-but-dies-almost-immediately-107673/ Fri, 20 Mar 2026 11:57:53 GMT My Blazer ZR2 2004 cranks and spits for a second then stops as if it isn?t getting fuel.

The vehicle is hot wired and I am thinking that it is causing the problem, but I cannot figure out how to bypass it especially since it?s giving the same voltage with the car in ?ON? and ?START? (2.00v) so I do not understand, I am planning on just replacing the whole key and mechanism this weekend.

Ive replaced Fuel Filter, Fuel Pump, Crankshaft Position Sensor, Battery and even tried spraying starting fluid, and jumping the relays to no avail.

let know if I am doing anything wrong, anything I haven?t tried so I can attempt something new.
