TJ, ignore the modulator vacuum line. That won't make it slip, that will make HARSH shifts.

Changing the fluid has never doomed a trans that we've ever seen here. But what do you have to lose? You have no first gear anyway.

Either get a flush, or drop the pan and do the filter. That'll only get about a third of the fluid, but it might be enough.

actually i have first now, but for how long is the question. It is werid how this came along so quick. No signs or syptoms. I am going to probably drop the pan and do a filter change then drive for about a month (if it last) and drop the pan and do it again. That should be about 1/2 the fluid correct? I guess it cant hurt. Does anyone have any ideas about the gt tranny? Is there anything besides the gearing the pcm i have to do if it comes to this?

My trans was slipping on take off from a cold stop every now and then and I changed the fluid/fliter and it went away. Not exactly the same problem but I think you really don't have anything to loose with changing the fluid.
And as for a GP tranny. Nope. They are 65s and require a different pcm to control line pressure. You could get a 3.33 diff though. Thats a whole other topic though.

Ben has a '95 4T60-E in his 97.... No re-wiring required. The thing to watch out for with later model transmissions is the PWM TCC solenoid and if yours is the same setup... I think... Hope this is more useful information than useless.

I never tried it but before you change the fluid you could try the Lucas additive. Some on the BC have used it sucessfully. Run it a week then change the fluid and filter.
I allways view trans additives as a last resort fix. If its starts slipping again what do you have to loose.
