Hi Guys.
This is a fairly common problem in series 2 & 3 Tri-Matics. The valve you mention is often called the dump valve & it's a small peice if plastic that restricts oil flow & one direction & allows quick flow in the other (slow apply, quick releas |

Hi Guys.
The HQ Tri-Matic does not have the little dump valve, It's in series 2 & 3 which is in HX onwards.
Honestly, it's not an expensive job, let the pros do it, & have it looked at & serviced at the same time. Get some quotes.

For those wondering, I eventually nutted out the location of the "dump Valve" Located between the valve body spacer plate and the transmission casting. It locates in a hole in the said plate on one end and fits in the bottom of the transmission casting, C
