i swaped in a 87 l98 350 tpi from a firebird in to my 91 camaro RS it runs fine i have no speedo or gas gauge or tach what do i need to do to get everything working ?

 

I think you will get some help if you go back and edit your post.

It is one big run on sentence that seems to resemble a crossword puzzle.

 

any idea's

 

Well, I hope that you didn't remove the 91 speedo electric connection because to get the speedo working you most remove the tail shaft out off your old 91 transmission and remove the metal speedo gear out of the output shaft. Then do the same on the 87 tranny wich it's plastic. Install the metal gear on the 87, also remove the magnetic pickup out of the 91 tail shaft and install it where the cable and gear goes on the 87. Reconnect the electric plug from your old harness in to the magnetic pickup.

 

the 700 r4 tranny out of the 87 uses vss senser no cable the wire harness is hooked up from tranny to ecm harness to dash harness
----------
note i installed all the engine harness in the car i did not change dash harness cus i thought it would work

 

You might need the VSS Buffer. 90-92 TPI cars had it built into the ECM (not sure if the V6 and TBI cars had in the ecm or not).


Do you have access to a scanner to see if the ECM is getting a speed reading from the trans?

 

i remember that in the firebird when i was taking out the ecm harness i will check in the morning in the camaro i do have a snap on soulis i will take that allso

 

okay my camaro dose not have the yellow box now i put all the wiring from engine tranny to ecm from the firebird how do i hook up that box to my 91 v6 3.1 dash wiring ?




ps the ecm is seeing readings from vss it not moving my gauge

 

I'll look in my service manual for the schematic and post a picture of it.
It will be late tomorrow night.
I just finished swapping out my clutch master cylinder and am about to jump in the shower then hit the sack (shot two weddings today and finished up my car. I am beat.)
tomorrow I'll be getting up early for the autocross (be there at 7:30am), then off to a birthday party/cookout.
