valve body and torque convertor ??

level ten will do just about any automatic tranny but they are REALLY expensive, like 3500 dollars

There is a guy named don that is from maximas.org that has a business called mobiltek www.mobiletek.net you send him your valve body from your transmission and about 450-500 bux and he will rework it so your car shifts much more firm and positive feeling. (no slip between shifts at all)

Protorque make a higher stall torque convertor. www.protorque.com expect to pay 350 dollars or so for one of these.

I would go the mobiletek/protorque route rather than the level ten route. More cost effective even when you figure in labor if you pay to have your work done. Osama has the mobiletek upgrade and his car shifts awesome, I have driven it.

*edit mobiletek has link and a very informative description of protorque's torque convertor and torque convertor's in general*

Shit bro you found what i been calling a ton of people about thanks. I even tryed to bribe jaspers tranny to experiment on a nissan tranny ide send them and i offered 2grand they said nope..

Since i thought there wasnt a shift kit fo our tranny i looked hardcore for someone to grind the valve bodies and all said NO!
thanks agian YOU rock bro..

There is a shift kit, it is from level ten...1200 bucks. www.levelten.com
If you have two grand to throw into the tranny, I would sell yours, and take that money, (probally like 1000+ dollars) and buy a level ten tranny with VB, new stronger seals and gears, super pump, and a TC. Your tranny would be awesome, probally just as good as most 5 speed drivers, but someone who really knows how to drive a stick might be slightly (just slightly) better.

Actually a full on level 10 transmission cost about $3100-$4400 depending on the vehicle and the work involved. You have to send them your entire transmission and they work on it and send it back. Expect them to have your unit for 6-10 days.

YUBYUB i chked there site and i think ill get this tranny i saw in junkyard fo 300 and order there rebuild and converter to come in same time as i send in the valve bodys. so i can get it all back and build it myself..
