Does your 1st Gen automatically downshift on hills???

I thought I was tripping when I first saw, but I saw it again today. I let off the gas and let her run down a steep hill. Sure enough, she shifted down to 4th holding the truck at 45 and 3k rpms.

If this isn't "normal," my only thoughts are the p2445\p0418 codes that are triggering limp mode. I do have lsd in the truck with no button (mechanical).

Only other thing happening is the beeping 4low. 4hi works, but not 4low.

TIA

 

It’s normal.

 

Well I'll be damned.. That's pretty cool actually!

 

It’s a nice feature. Does it if you tap the brake downhill as well.

 

I didn't know that. Good info.

 

Yep my sequoia and my bro in laws 06 Tundra does it. I really like the feature.

 

Not positive if the 4 speed does the same.

 

Lift me up just to smack me back down. Thanks.

 

I’ve never driven the A340F so not sure if it acts the same but it could.

 

I'll try it out. There's a hill about 3 miles away I can try it on. Gotta love prairie land...

 

I think it's a 5 speed thang.
At least my 4 speed doesnt do that.

 

Isn't 05 the first year of the 5spd Auto?

 

Yes

 

Been driving the 02’ (4 speed LSD) forever and do not recall it having this cool feature.

 

I’ve driven two different early 1st gens with the 4 speed and have never seen that.

 

Hmm i’m going to drive my 03 today I swear it does it. But I have only driven it a few times usually the wife drives it. I think I’ve rode in my brothers 06 more than I’ve ridden in my Sequoia. Maybe it’s because he always comments when his truck does it LOL.

 

I couldn’t try it on any hills but it does not appear that my 03 does it. Usually i have TH and OD off that may have been what I was feeling.

 

Not all models have it.
It is a function of the vsc I think. I know it was an option that not all trucks have, and was not a standard feature any of the trims. I had a 06' limited with it and I loved the downshift feature.

 

I’ve got to try it down a hill.

 

my 04 does not do this, however, I can use the Overdrive switch to slow down the tranny on steep hills, but it will not hold a fixed speed.

 

My 05 Does the same thing

 

My 06 does it- first vehicle ever that knows this trick!

 

My 05 does it.
