After Transgo Kit 2nd Gear Bangs!

installed a transgo reprogramming kit in my 60e some time ago along with a tci servo. wayyyyy to hard of a 2nd gear. figured it was from the servo and kit coupled up. took out servo. still to hard. reduced down to 1 washer under accumulator spring. still hard but at 30-40% throttle only. wide open its quick but not rough, wont chirp tires. but first start in the morning and pulling out in traffic and it will snap your neck with very modest acceleration. baby it and your ok. any ideas from the transmission experts????

maybe line pressure by tuning would solve it

i had alan tune it, and asked if he could lower the shift pressure and explained my issue. he says he can only increase not decrease. feel that would only make it worse...

it would be great for my camaro, but not for my daily driver. although it sounds mean, it can me funny watching my kiddo's head during shifts.

Take all the washers out and put the servo back in... Thats how mine is and its just a quick little snap..

I picked up new filter and gasket so I'm going to try removing the washer first. If it's too sloppy after that, I'll put the servo back and give it a try. If that doesn't work. I'm swapping in a 80e!

Nope. It's been out to do the trans go kit with the front pump mods and valve body stuff but that's it. Well it's got a converter. But shafts and internals are stock.

Yeah, do the new filter, gasket, and washer removal. Every Trans-go shift kit I have installed has ended up with no washer cause even one is too much.

I would honestly leave the tranny pressures where they are. If you want firmer shifts after you take out all washers, then manually turn up the EPC. I think it uses a really small Alan (hex) head wrench. If you do this, only turn it like a 1/4 of a turn. If it is still too soft, crank it up another 1/8th of a turn or so. I know that its a PITA to keep on draining the fluid and dropping the pan to get the correct firmness, but it the tranny pressures are stock in the tune and the EPC has not been adjusted, then a 1/4 to a 1/3 of a turn is prolly fine.

Havn't you blown up like 15 in the last year? Doesn't make you too credible in the transmission advice area.

I personally have not burned up the 3/4 clutches myself. It was an electrical gremlin. Dipchit.

A few things come to mind when I hear a complaint like yours. There are three things in that shift kit that effect the 1-2 shift.

First is the obvious the feed hole size. In a truck I would drill it to the smaller size in the directions.

Second is the 1-2 accumulator valve spring they have you install. I have seen where the valve and sleeve stick and do weird stuff. Also make sure that you did not install it upside down. It is easy to do and most guys do it by accident.

Third is the 1-2 accumulator piston setup. I read constantly where guys say too remove all the washers. The issue here is that in late model 4l60E's the housing changed. There is not the proper surface area to support the gold spring seat. It basically get all bent up and does not do what it is supposed to do.

In your case I would return the factory springs back into the housing in the OE configuration. This in most cases fixes the issue you are having. Hope this helps. Vince
