New to The Diesel World

[ASchwartz]

I have a 94 2500HD 4X4, 5 speed. At 70 mph, I am running 2000 rpm and it sounds like I need to shift into another gear. At 85 mph the governor kicks in. I am not sure what my gear ratio is. What can I do to fix this problem.

2000 at 70 sounds about right based on what I see in my truck (see my signature). I am not sure about a governor at 85... haven't experienced that.

I have a 96 I that sounds like the 3. 54 gear. No way it could be the 4. 10 I know my buddies runs like 2. 3-2. 4k at 70 on his 96 4x4 5 speed.

Yep 85-90 is where the speed limiter kicks in.

Fixxing it? hmm slow down its a diesel not a race car. The pump can be adjusted I am told but unsure how or if you would have to send it to someone.

This morning on my drive to work, a Ford Ranger stayed with me up a substantial grade. Any advice?

Maybe he was Bomb'ed!

I believe you have the 4:10 ratio I had a 94 1 ton 4X4 /w/ the 5-speed and it would really wind up on the interstate. It also topped out at about 90. The 96 that I have /w/ 3;54 ratio runs about 1800 r. p. m. at 60 m. p. h. and it's an auto. to boot, also 85 go's by pretty easy. unless someone has removed it there should be a sticker under your hood up by the grill with some paint info. on it and the gear ratio should be there also.
