beefing up a trimatic

hi guys

I guess this QU has been asked over and over in the old forum but I could not see much on it in this one so sorry if its a repeat

anyway what can be do to them on a tight budget?

I know in a perfect world I would take it to the shop and spend lots and lots of money and have a tough tri matic in the end

but what basic mods can I do from home ( if any ) to tighten it up a bit?

for a start I am looking into a high stall for it some ware around 2600 to 2800.

Just out of interest has any heard of this...

I read in a book called "building a holden" published by clockwork media, they have an write up in it that says you can drill out two holes in the second and third clutchs of a trimatic that will tighten ( speed up) the shifts from 1st to 2nd and 2nd to 3rd. the book gives a step by step with pics so it does not look that hard.
I guess it kind of the same idea as a shift kit?
Has any tryed this or something like it?

any advice on whats best to do would be great

thanks agian antony

With a shift kit they usually drill holes in the transfer plate under the valvebody and change a spring on the check ball, This is the way they increase shift speed and line pressure. You can rip out the wave spring in the clutch packs and add extra friction plates and steels which will give you stronger clutch too (you can get 7-6-5 plates in the clutch packs, max stock ones had 5-5-4 from a statesman). On mine they replaced the servo with a billet item so that it won't fail under the increased line pressure.
