k so i gots me an issue and wonderin if there is a sensor of some sort on my tranny cuz every now and again cept for the past couple days its been non stop... my speedo and my tach quit workin it says check guages and its like my truck takes off in 3rd gear what could be the issue?

and also i have had the both battery and alt. checked and they are good
it has tranny fluid and there was a tranny line that was leakin but i hav also got that fixed

 

ive also checked fuses and tried resetting everything by disconnecting the battery and still nothin same ol crap

so if anyone knows what my problem is or if you have had or are having this problem lemme know i could really use the help on this one

 

as far as tranny not shifting right, or starting in 1st, i'd suspect fluid level/condition, filter condition, and possibly the detent cable (from throttle body to trans) this cable has a certain adjustment it needs.

for the gauges, only other thing i could think would be a ground issue somewhere. the speedo gets a signal from the computer, which gets its signal from the trans. the tach gets its signal ultimately from the coil, by way of the computer. maybe check the backside of gauge panel where it plugs in, make sure connectors are ok.

 

i have a 98 and the speedo quit also, i first replaced the VSS vehicle speed sensor located on the back of the transfer case, that didnt fix mine and i ended up getting a whole cluster out of the junk yard. If you truck has the 4l60e transmission, you wont have a detent or TV throttle valve cable, the 4l60e is electronicly controlled and part of the signal it uses is from the VSS.

 

did your truck also stay in 3rd gear

 

no it did not stay in 3rd gear. Is your fluid at the correct level while hot, wipe the dipstick on a white napkin, is it cherry red or brown, does it smell burnt.

 

Here are a few liks that might help troubleshoot

yes it is at the correct level while hot and it is red

 

ok was out checkin fuses and stuff and found out that if i put it into 3rd with the colum the check gauges light goes off but when i put it into other gears 12DNP the check gauges light will come back on
but still wont shift outta 3rd and tach and speedo still dont work

 

and ive also checked ground wires and they are all tight and grounded propperly
