OP,
Is your truck a 4x4? Is your transfer-case stuck in low range?

 

Hi I seen your post and had a couple questions my truck is a 1997 4.6 4x4 when I get up to 35-40 mph it kinda starts to hop lightly and the rpms raise but my speed won't... It seems to shift in all gears really fast?? The 4x4 light won't come on unless I switch it on and off a few times but it doesn't kick on underneath if I'm describing it right. I'm trying to figure out the problem. I just bought it a few months ago and haven't gotten far

 

Hello, I have this problem. unless I disable OD by pushing OD button truck will not go over 40 mph.
I removed transmission pan and removed valve body and I found that snap ring on reverse was broken..and few pieces were in the grooves of valve body ( I dont remember where exactly they were) ..overdrive servo (snap ring) was not broken...
Do you think this broken reverse snap ring(servo) is the reason why ...it wont go pass 40 mph unless OD is disabled?
I replaced 1-2 and 2-3 accumulator and piston and that broken reverse snap ring but have not touched overdrive section.
Do you think I should remove overdrive snap ring and check if spring inside is ok?

 

The first thing to do in that situation is to check the trans fluid which may be very low. You could have developed a leak in the trans cooling lines. If the fluid is not low, you probably should have it towed in. If the fluid is low, add trans fluid and have the fluid changed when you can, assuming it hasn't been done in 50,000 miles.

)I am having the same issue. (Hello, I have this problem. unless I disable OD by pushing OD button truck will not go over 40 mph.)

Did you get yours figured out?

 

Hi, I just wanted to know did you figure out your problem, I myself are having these issues, my truck doesn't accelerate past 30 unless I turn OD/off, which gives me 40mph, and check engine light hasn't came on. I have been told to change out the transmission solenoids, I'm just not convinced that's the problem. So what did you end up doing?

 

I missed this one in December. You might want to start a new thread for this issue just for visibility. Tagging onto the end of a seven year old thread probably won't cause any fresh eyes to look at it. The thread starter, Deborrah, hasn't posted anything else in almost eight years so it has likely fallen off their radar.
