ryangregory_86 Posted October 15, 2009 Report Posted October 15, 2009 Got an AE92 with the 4AF-C Engine and a 3 Speed Auto, I believe they're the A130L. My Tranny is Dead (Left without Fluid for WAY to long I Believe) And I am planning on replacing it very shorly because I miss my car... ANYWAY, Is there a 4 Speed Auto that will bolt straight up without much hassle, I plan on doing the work myself so the easier the better. That being said I am pretty handy so a small abount of rewiring etc will not be a problem What are my options...... Any Help Much Appreciated Quote
clubby2084 Posted October 18, 2009 Report Posted October 18, 2009 High spec AE92's came out with a 4 speed O/D auto, CSX, Ultima etc. The 4 speed fits easy enough, but, you'll need the gear selector for inside the car as it has the button for the O/Drive. From what I've have been told with mine, the first 3 speeds are hydrolic but the 4th gear and lock up function on the torque converter is electronic, so the gearbox has a computer to control the 4th gear and the lockup function on the torque converter. You'll need that too. Without it you'll still have a 3 speed. Quote
clubby2084 Posted October 18, 2009 Report Posted October 18, 2009 Also, forgot to mention. The thermostat housing is different as well. There is a temp sensor for the O/Drive mounted on the thermostat housing. Need to have that too. Quote
zimtoy Posted November 14, 2009 Report Posted November 14, 2009 Just bought a very nice Seca with 3 speed auto To convert to 4 speed do I require a completly new box. What did you eventually do Quote
clubby2084 Posted November 15, 2009 Report Posted November 15, 2009 I bought the 4sp from a wrecker by mistake. Thinking I was buying a 3 speed. My mate is a mechanic and he did the swap for me. It is a straight swap, gearbox wise. The 4 sp is a physically larger unit but hooks up to the same mount points, bolt holes etc. I did buy new gearbox mounts for a 4sp while I was at it. To be honest I didn't take any notice if they were different. The only thing I had to source was the thermostat housing and the auto's temp sensor (temp sensors are over $400 genuine, so look around for a good 2nd hand item). I also bought a new torque converter. And the gear lever and computer I've mentioned (got these from the same wreckers) Drive shafts hooked up no problems. The whole job took 3 days (after work). The thing looks and feels factory. The result is brilliant. 2200rpm at 110km/h. The car is now a great cruiser rather than a roudy buzz box. Quote
