Transmission concern

Hi guys, i have a 1992 ford f150, 2WD with the 5.0l 302. i recently noticed that when i give the truck alot of throttle to get up to speed, the transmission will shift twice from 2nd into 4th. this only happens when I accelerate quickly. when i take my time getting up to speed, it works perfectly. The truck only has 85,000 miles so its strange that it would have a transmission issue like this. is it possible that it is just the way the truck is geared?

all help appreciated!!!
thanks in advance!

Do you mean it shifts from 2nd directly into 4th, skipping 3rd? When was the last time the tranny fluid was flushed and filter changed? That would be my first step, flush and change the filter.

first step: pull codes. Let the truck tell you where to look, don't wast your money by trowing parts at it.

Then change the filter and fluid if you cant recall the last time it was done.

The truck reads no codes transmission related as far as i can tell. Fluid and filter is defiantly where ill start. is the truck safe to run until i fix this, or should i leave it where it sits?

There should be two shifts. 2-3, torque converter lock, then 3-4. New fluid should make this smoother so that it is less noticeable.

Now that I re-read this I'm confused. You're complaining that there are two shifts from second to fourth? Shouldn't it shift 2-3 and then 3-4? Isn't that two shifts?
