Will GM 200r4 work with factory floor shift location?
Well the day has finally arrived. Starting tomorrow I will put the Barracuda on the lift and start removing the 904 tranny. I would have liked to have done it weeks ago but the friend who has the lift promised that if I helped him finish his 1940 Hot Rod he would help me with the tranny and let me use his shop. We all but finished his hot rod so now I get to replace my tranny.
I'm not writing to update everyone about the tranny swap....I'm writing to let you know about something I discovered as I was replacing my speedometer last week. My speedo has been bouncing (below 40 MPH) ever since I bought the Cuda many years ago. It has been a thorn in my side and I've wanted to fix it for a long time. I bought a used factory 140 MPH speedo and had it refurbished. I also had a leak in my AC/heater control vacuum assy. So I finally pulled the instrument panel and replaced the speedo and the AC control assy. And yes I had already removed the cable and lubricated it but it didn't help at all. Anyway, as I was putting in the new speedo on the bench I noticed that the speedo cable connection on the 140 MPH speedo was different than mine. I had to do a little research on this problem because there was no way my push on cable was going to screw onto the new speedo. I have an all original '69 Barracuda and it comes with the push on clip type speedo cable. I've known this fact for some time (from when I lubed the cable) but when I bought the new speedo I never even looked at the back side because I thought all Barracuda (67, 68,69) speedos were the same. Unfortunately I had my instrument panel out and was committed. I put the new speedo into the panel and put the panel back in the car and went home for the day. When I got home I did some research....as it turns out the Barracuda speedos prior to '69 had the screw on type cable connection. I found out that the speedo cable connection on the back of the 67 and 68 speedos is the exactly the same as many other cars (Ford, Chevy, etc) 5/8"-18 thds. If you remember what I wrote about the tranny cable connection (months ago) you'll know that the Mopar and Chevy (and many other cars) have a similar connection on the tranny end of the cable. So...all I had to do to make my new speedo work was a standard Chevy, Ford, Mopar cable of the correct length. I went to O'reillys and asked them what different length cables they had for Chevys and they gave me a long list. I selected the 83" cable because when I install the 2004R I'll need a longer cable to reach the tranny connection (behind the trans cross member). It only cost $12 and they had it in stock!!! For anyone who does this tranny swap remember, if you have a clip on speedo you'll either need to get a longer clip on Mopar cable or get a cable extension (like I had already done). If you have a screw on type speedo you can use the standard Chevy, Ford, Mopar Cable in whatever length you need.
My speedo works perfect now and my AC/ heater assy no longer leaks any vacuum.........Getting closer to the perfect car!!!!! Can't wait to see how much the 2004R helps performance and gas mileage ESPECIALLY with the 4:10 gears!!!
