Hi folks, I'm pretty ignorant when it comes to trannies, and was wondering if someone with a bit of knowledge of modern auto trannies might help me out. Am I correct in assuming that most newer auto trans (maybe even old ones too?) use a single solenoid to control the flow of oil, which determines the shifting of the tranny? If so, is it possible to control the shift points of the tranny, assuming that you eliminate the stock programming in the tranny ECU? I was just thinking that one could hook up a switch to that shifting solenoid and shift "manually"...or maybe it can still be done, but another way? Any help would be great.....!

On a 4 speed auto trans (GM is where I get my experience), there are 2 solenoids... The trans will shift itself if the engine is revved high enough without input from the solenoids by governor pressure, and re-programming can be done if you know where the tables are in the chip... The modern GM 4spd Auto's have the 2 shift solenoids, a torque converter clutch lock-up solenoid and a line pressure modulator. You can vary the firmness of the shifts along with where the shifts occur. =========================================================== David Cooley N5XMT Internet: N5XMT@xxx.net Packet: N5XMT@xxx.

Most use at least 3 solenoids, if memory serves me correctly. Manual shifting could be accomplished with a bit of head-scratching and logic. ------------------------------ Date: Sun, 30 May 1999 22:55:01 -0400 From: "Scott Flanagan" Subject: 1227749 Adaptation Hello, I am about to adapt a 1227749 ecm to a Fiat Spider and I had a few concerns to ask. One is the Vehicle Speed Sensor, can I do without it, do I need to just tell the ecu it is not there, I noticed in Programmer98 there is a function to turn it off, is that all I need to do? Also, should I set up the ignition of the fuel injection first? Which one would be considered more stand alone? One more question, would I be praying too much for the car to at least idle and halfway run on a stock rom file? They are both 2.0L, Overhead cam. Or, am I just asking for too much?

Howdy Lyndon, It calculates the power that your engine produces, however its real power, at the wheels, because it requires other information other than just listening to the engine... so it takes into consideration load. However, it cannot distinguish the difference between an aerodynamically "perfect" 6000lb car versus a 3000lb aerodynamically "embarrassing" car... load is load, and the software doesn't break that apart... though you do enter your vehicle's weight and other parameters. Its close though, damn close ! ------------------------------ Date: Tue, 01 Jun 1999 03:12:50 -0400 From: Frederic Breitwieser Subject: Re: laptop HP measurement (Was g meter) > Well...okay.

One of the advantages of this system is you can record using a tape recorder, then dump it into your sound card later on, though you get more "noise" in the signal. Use high quality tapes. However some racing classes don't want to see gizmos and electronic stuff, which a tape recorder is of course, but easier to hide than a laptop. Duct tape under the dash comes to mind :) ------------------------------ End of DIY_EFI Digest V4 #323 ***************************** To subscribe to DIY_EFI-Digest, send the command: subscribe diy_efi-digest in the body of a message to "Majordomo@xxx.
