<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">Last year I requested
your help regarding a strange overdrive or slippage problem I have in my 1962
Tricarb BT7. </span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">I received very
valuable comments and suggestions but sadly the problem persists: Overdrive
would not activate under any circumstances and when the engine / transmission
is warm and we engage reverse, the engine revs but the car won´t move. </span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">There is slippage
somewhere in the transmission / clutch or overdrive. When the car is cold,
reverse engages without any issues. This only happens in reverse gear after the
car has been driven a few miles and the engine and transmission are warm.
Forward gears engage all the time without any issues.</span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The car has been
recently restored. Before the restoration the overdrive was operational. Now
it’s not. </span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The transmission and
overdrive have been taken apart and assembled twice looking for something
visually wrong. Everything seemed to be OK.</span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">The clutch and plate
were also removed for inspection. The clutch was recently redone, adjusted and
tested.</span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">A friend suggested we
should verify the oil pressure on the overdrive. On this link you will find a
couple of videos of a test we have recently done with a manometer installed on
the overdrive to check the oil pressure at different RPM´s. </span></p>

<p class="ydpfe39e09bMsoNormal"><span>The pressure on 3rd and 4th gears goes up
to 400 psi and drops as it goes to lower gears. At idle is between 150 to 200
psi</span></p>
<p class="ydpfe39e09bxyiv3660242746msonormal" style="background:white"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif">In forward gears the
car runs fine; the problem that we need to solve is that the overdrive would not
activate(even though it is connected and everything seems visually OK) and the
slippage we have when engaging reverse (the car won´t move) when the engine /
transmission is warm.</span></p>
