3rd gen 4 cyl. tranny

Posting this here, got no bites in the 4 cyl forum

When I accelerate under medium throttle where trucks shifts around 3500-4000, when the truck shifts into 3rd gear the truck halfway falls on its face. Drops 800 or so rpms. Normal? Auto trans

 

3500 to 1000 (3.5x) on a 2nd to 3rd shift doesn’t sound normal for any car including a taco. Are you sure you have your numbers right?

For comparison sake, the 2nd post in this thread has the transmission gear ratios for the 3.5 auto and manual transmissions. If you look around you should be able to find the ratios for that 4 banger.

 

No, drops about 800 rpm from 3500 -4000 into 3rd. So drops about to 2500-3000 when going into 3rd. Not all the way to 800 rpm. Enough that it takes the momentum away when merging into traffic

 

What happens with more throttle?

 

I misread. A 22% drop seems reasonable.

I’m not sure why you are asking your question. You can look up the gear ratios for your truck.

 

Here you go.

4th to 5th is usually the big drop not so much through 1-4. i have a 2.7 with a re gear, header, and tune, keep the tire size skinny and get a tune at the least will make it drive a lot better

 

I think your assumptions are off the mark. Check the gear ratios I linked.
