Help! Crusing @ 60mph 5th gear 4000 revs

[slammin.e28]

I'm telling you - there is no way a 4.10 will do 4000rpm at 60mph. Not unless you're running rubber band tires on 13" wheels.

This.

Swap in a good cluster and see what it reads. Easiest diag IMO.



You say you have a Euro cluster? Maybe it's in metric RPMs? ;)



JK.

Your speedo is wrong you're actually doing 85 :P

[LJ851]

Perhaps you have a close ratio gearbox. How do you engage 1st gear?

He said he drove next to someone who verified the speed.

^ I have lined up and done that already, I have also used gps to measure my speed though its not accurate it reads 56-60mph its not that far off

the only think I can think of is if you have an eta coding plug in an I tach

[supkev]

I will look into it

Hey guys, i have the same problem, i just recently swapped in a 4.10 in to my 327 stoker with a gearbox from a 325e, my 1st gear redlines at 20mph 2nd is around 45.... no idea how to solve it, i am sure its the diff, i was fine before the swap

What is your rev limit? A 4.10 is good for a lot more than 20/45 if you have a 6500-7000 rpm limit. Did you forget to change your cluster, or put in one from a 4 cylinder?

[nrubenstein]

A quick check suggests you have a 4-cylinder plug. You could check by seeing if the engine stops revving at the redline on the cluster, or way past. I'll bet you hit "7k" and keep going.

i did change my cluster, but ill try going pass 7, wat i also did was the swap sensors from my stock diff and placed it in the 4.10 so i woulnd have to cut the connectors, that the only thing i can think off that may though it off

What's your redline? you should be able to do 30-35 in 1st and 50-60 in 2nd, depending on tire diameter and the actual limit.

[Bahama325]

My red line is 7gs, after reviewing the two sensors there is a big difference, i think that is the culprit, i am going to replace, on the stock diff the sensors are uneven and on the 4.10 they are even.
