Re: blazer rolling slowly when in park
Are you sure its in park and not reverse. the linkage on these blazers get really loose on alot of them. an indication of worn linkage is you have to play with the shifter to start the truck now and then.
check that first. do you know how to manualy put the truck in park without the shifter? if you do i would do that to make sure and rule out inaccurate shift indicator.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Whats happening is when you go into drive the transfer case spins but is not in gear and then when you go into park the gears are grinding, because the transfer case is spinning, its like trying to go into park while the wheels are spinning, the transfer case is in neutral you need to adjust it, and make sure the adjustment is right or you may be in 4wd low instaed of 2wd so after the adjustment check and postions of the 4wd.
Yes it can, just place your Transfer Case in Neutral position.
Shifting into NEUTRAL To shift the transfer case to NEUTRAL do the following:
Make sure the vehicle is parked so that it will not roll. Set the parking brake. Start the vehicle or turn the ignition to RUN. Connect the vehicle to the towing vehicle. Put the transmission in NEUTRAL (N). Shift the transfer case to 2HI. Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete. Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles equipped with a manual transmission. Turn the ignition to LOCK. Place the transmission shift lever in PARK (P), or FIRST (1) for vehicles with a manual transmission. Release the parking brake prior to towing. Shifting Out of NEUTRAL To shift out of NEUTRAL:
Set the parking brake and apply the regular brake pedal. Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off. Press the button for the desired transfer case shift position (2HI, 4HI, AUTO 4WD or 4LO). After the transfer case has shifted out of NEUTRAL the red light will go out. Release the parking brake. You may start the engine and shift the transmission to the desired position. Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes. NEUTRAL: Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle. Good luck and hope this answers your question.
park on level ground engage emergeny brake and chock wheels
locate transmission cable at trans linkage on side of trans. loosen the
cable clamp push cable+linkage arm all the way into the park posistion
tighten the cable clamp it also helps to have an extra pair of hands up
top to move shift lever so you can inspect it from below also make
sure linkage arm is not slipping on the shaft that go's into the trans.
if you have to jack it up for extra room please use a JACK STAND.
if you need help locating any of the parts mentioned stop by any
auto parts store and pu a haynes repair manual for your trk. it will
give the step by steps and diagrams for this job + many that may
come up in the future.
hope this helps any other ? gimme a shout good luck
i would say the fine grinding was when you put it in park the output shaft was turning and the parking paw was trying to engage into park then the paw engaged into park but you say it rolled i am thinking that your problem is in the transfercase
When you place your vehicle in park, a metal bar slides into one of many large slots on an internal drum in the transmission. If the slots or bar are worn, or if the differential or universal joints are worn, that play has to be taken up before the vehicle will not roll further.
Hey there..my name is Keith..and in your transmission..there is a parking cog..and its not in your transfer case..and either its wore out..or you vehicle needs some shift linkage adjustment..or the linkage has gotten bent from 4 wheeling..and i hope this helps..if not..please write back
sorry but your stuck with the 4l60e if you want it to be right. as for using the bravada transmission thats fine you just have to use your transfer case. your transfer case uses a switch on the dash and an electric motor on the transfer case. the bravada uses a series of sensors on the front and rear axle that sense wheel slippage and send a signal to the electric motor on the transfer case causing it to lock in four wheel drive. when the sensors dont sense wheel slippage any more the system returns to two wheel drive. that,s why they call it smart track. just unbolt your transfer case from your transmission and bolt it to the bravada transmission and install it. p.s- dont forget to at least change the front pump converter seal. for 4 or 5 bucks it,s cheap insurance against a major leak and i dont think you want to pull that transmission out again and yes i saw that happen to many times. good luck.-G.J.M
