Truck feels like it's under a load and not wanting to move

FLETCHxj · 11-20-2012, 08:18 AM

Well last night I did the LED cluster swap and when I went to leave this morning for school it feels as if I'm hooked up to huge loaded trailer but it will still idle forward as usual. I thought it was in limp mode so I hooked a buddy's insight up and cleared all the codes but it still isn't working right. It feels like the brakes might be locked up but how could they be when it can still idle forward easily? Any one have any ideas?

you can drive the trucks with out the gauge cluster, changing leds isnt going to change anything on how it drives. Are you getting any codes?

It's showing U1026 which is a loss of communications with the transfer case control module

It also says it's in 4 low and it won't go back into 2wd

Check the ignition fuses...that code is for transmission module

just check all the fuses

I just checked them all and the only ones that aren't working are BTSI and CRNK. The fuses looked good but I replaced them anyways and they're still not getting power.

Is your transfercase solenoid making any noise like its trying to change over then just quit?
Its pretty common for the transfercase solenoid to go out after a while on these trucks.

The only indicator light is the battery light and the check engine light.
