Q. What kind of gauge do I need to check line pressure.?

A. 0-300 psi with a decent line to ensure no leaks!



Q. The soleniod on the transbrake activates, but when I put it in low gear and apply it, it does not engage.
Does this sound like a pump problem?

A. not necesarily....if the solenoid does engage (and I am presuming the correct valve was installed into the valve body under the solenoid...yes, I have seen them left out..lol!!) then you have some sort of hydraulic issue. First confirm line pressure at the low servo port as first mentioned. Once I have some pressure readings to go on we can move along the diagnosis from there....also take a peek at my site Oldani Motorsports and click on the 'trans tips' page. Scroll down and look at the photo which shows the governor support and tin plate/gasket to use...this is for the 'pro' brake which is the one where you must push the button to back up. BUT, there are some mismatches that can occur with a non-pro brake that will leak reverse circuit pressure out the governor support. You need to pull the support and verify no leakage as some cases feed reverse down at the 7:00 position as viewed from the rear of the car and others feed through the support and into the case at the 11:00 position. If you have a mismatched support/gasket/etc. it can lose reverse pressure there, but that would have NOTHING to do with not having low or second gears. That is why you need to FIRST check line pressures!!! Hope this helps!!!
