I bought a car that already had a TH350 swapped into it (91 RS). How can I get my speedometer to work?

Let me know if you ever figure it out. I swapped one in 6 mths ago and haven't had a speedo since.

i believe if you call tci they will tell you what gears to put in the tailhousing depending on what gear ratio and tires size you have

Where would I buy the gears?

Are the 91's cable speedo's? When i put the TH350 in my car, my speedo cable screwed right on to the housing...

91-92 or maybe 90-92 is electronic

If it's a cable driven speedo, just hook it back up. Could probably swap in the plastic gears from the old trans. If it's electric, they make things that use the gears and output an electronic signal.

SO then, will I need an aftermarket cable driven speedometer? Should I just start looking to custom make a cluster? Or can you run am electronic speedo to a TH350? I was wanting to do an all digital dash but the TH350 may make that impossible.

What fast82z said, they sell adapters to convert it
