Sources for finding trans component specs and info

A forum for discussing applications and implementations of the MegaShift transmission controller code for the GPIO from B&G. This can control up to 8-speeds and 6 shift solenoids (plus a 16x9 table for controlling a PWM line pressure valve). It has manual and fully automatic modes (16x9 load x speed table), with under and over rev-limit protection, and full data logging of all inputs and outputs (among many other abilities). A TransStim to test your completed board is also available.

Sources for finding trans component specs and info

Post by ntstlgl1970 »

Here are a couple of sites that I used to find specs on shift solenoids, temp sensors, linear solenoids, hards parts etc. that may be useful to other members setting up megashift.

http://www.rostra.com/transmissions.htm - download the catalog, has specs on many components and picture images as well as harness pigtail info
http://www.transgo.org/ - sign up for the one day free trial for tech tips, has lots of pinout info for connectors and sensor specs etc.
http://www.transtarindustries.com/catView.asp?ID=444 - transtar trans rebuilding parts (all over the US) you can order electrical parts from here and pick up locally in most metropolitan areas for less usually than online specialty sites
http://www.bulkpart.com/Merchant2/merch ... ore_Code=2 - about the least expensive online trans parts site I've found if you are familiar with hard parts or know what electrical parts you need. Not the most user friendly interface.
http://www.sonnax.com/tech_info.php - good tech tips for transmission related issues that may or not be related to elecronic control

Enjoy!

Hi everyone,

I can vouch for bulkpart.com. I bought a master rebuild kit and Transgo stage 2 kit for a TH400 earlier this year, and they were the cheapest source for this sort of thing (at least for consumers - I'm certain a professional could get a better deal somewhere). When the time comes to freshen up my 4L80E for the MegaShift project, I'll shop there again.

One small addition: The ATSG web site allows you to buy electronic copies of their manuals:
