Well you can say I told you so.After my aborted attempt at a mail order tranny(2 of them) that did not work right I have had my tranny rebuilt locally.Everything soft has been changed and it has a Zpac 3/4 clutch kit and a Trans-go shift kit in it.It works pretty good but has a couple of things I want to ask about.

1.What are the Mph points that the 2 gear downshift should occur?
currently it will down shift 3-1 below 30mph and 4-2 @62mph or lower I am trying to remember but I thought the 4-2 downshift occured at 65mph before mabey even 66mph.It will wind out in 2nd to 76mph and shift at 5krpm.Once it hits 3rd above 30mph it will only drop into 2nd.

2.What rpm should it upshift at. I know 1st is a little low at ~4600rpm,2nd@~5krpm(used to be closer to 5500rpm).I haven't wound out third yet.What needs to be done to get the right shift points.

3.The Trans go kit hits 1st pretty hard at light,medium and WOT.Should it be somewhat smooth at light throttle?The only way I can get it to shift without snapping my neck is to let off just before the 1-2 shift.Is this how it is supposed to work?Will it smooth out after break in?

I have a drip at the rear seal so it is going back on Monday and I want to be able to get fixed what I can at that time.Am I expecting too much?

Over all it makes quite a difference though the car is much smoother and gotta love the bark going into 2nd at WOT but because it bangs so hard at light throttle I am concerned I won't be able to drive it in winter weather.ASR kicks in every 1-2 shift on even damp roads.

 

I don't know how much help I can be but I will try. If memory serves, you have an electronic trans with no tv cable? I have done many 92 and prior, and a couple of 94 and ups. 93 always confuse me.

 

It is a 700R4/4L60 Pete.The 4L60E's came in 94.Thanks.

On the TV cable if it is shortened to smooth out the 1-2 shift I loose the WOT shifts at 5k to 4.5k,If I lengthen it to get higher rpm 1st shift the other gear shift points raise up too much and the 1-2 shift is really hard.

 

If memory serves, the wot upshift rpm is 5200 + or - 200 rpm. Every governor seems to be slightly different. The trans will shift into first(on manual down shift) at approx 36 mph.I will stick my nose in the gm book to try to find more specif info regarding the shift points. I also have never installed the transgo shift kit. Most of my customers are tight and do not want to spend the money. I do hear good things about it though. Suposedly, the advantage to the transgo is varying shift firmness based on throttle input. Light throttle should equal smooth shifts and wot = hard ones. The transgo kit alters the tv valve. I have a hunch your problem lies there. I recommend calling transgo. They are suposedly great with customer support. Also wiggle the yoke on the driveshaft. If the guy did not change the case bushing and or tailshaft bushing, it will prevent the seal from doing it's job. You will never hear me say "I told you so". The best plans always seem to take a turn for the worst sometimes. Hopefully the local guy knows his stuff, did you right, and simply had a bad day. Also, an auto trans has zero break in. It is usually it's best the first mile it goes down the road.

 

He replaced EVERY bushing in her Pete they did a really good job and showed me every part they replaced.The bushings were toast the lube grooves were almost non existant.I appreciate you looking in the book I would like to give him the hard info I am sure he is willing to fix it right( I paid $2k) and he was fuming at all the poser tranny guys around here(including the mail order ones he put in for me).So I expect him to be on the up and up about this.I just need the data to give to him as to what is correct.

 

You may not want to quote me when you talk to him. I am in the construction business by day. Transmission rebuilds are something I got involved with because:
1) I am very cheap
2) I got tired of paying good money to pro's for sh*tty work.
3) I enjoy the heck out of working with my hands. I am very detail oriented.
Although I could probably make a living doing transmissions, I would never pretend to know more than I do in this area. I will keep my snoot in the gm books and see what I find. Your guy sounds like a good one. Don't give up on him yet.

 

wish you were closer

 

I appreciate that I would tell you to mail a trans, but we all know how much I am against mail order transmissions

 

Not to steal the thread, but I've a problem within the discussion here -

1. My 99 coupe has only 20,XXX miles. A4 Tranny was running 200+ degrees in summer. I put on a B&M 24,000 BTU Tranny cooler. After that it was running 169-172 degrees.

2. I was told that when you put the Transgo shift kit, it clears some passages in the Tranny, and makes the shifts Quick and firm. THIS reduces the heat in tranny, therefore, making it run cooler.

3. I just put in the shift kit yesterday. I was hoping for neck-snapping shift (my mechanic told me I'd get after installing this kit), which didn't happen. Though, I did feel a verrry slight kick going from 1-2 gear, but thats it. He says car's PCM needs a full tune to benefit from this (another $500 for tune) .....After Transgo kit insatallation, now my Tranny TEMPS are running 210-215 degrees. The outside temps are much lower now than in Summer, so why is my Tranny TEMPS gone from 170 to 215 with Transgo Kit ? Wasn't it supposed to go lower according to what I was told. Even if it doesn't go down, why is it going up so dramatically?

I am very upset and disappointed with this... Plz tell me what's wrong here ? I will highly appreciate any inpute and advise. Thanks in advance.

 

I wish I knew why this caused increased temps. Common sense tells me it should not have. I usually install the b&m kits. They are cheap and effectively lock out the 1/2 and 3/4 accumulators. This gives a super firm shift. Almost too firm. I am tempted to buy and install a transgo kit just to see what(exactly)it does and what circuits it affects. I would check the lock up part of your torque converter. A lock up failure will cause increased temps.

 

Well I have a neck snapping shift with mine even on light throttle so mabey you did not use the right springs?The Transgo site has a FAQ and you can call them tomorrow and see what they say.

I had another tranny with the "trick shift" done to it which is the ugly way of drilling and pluging and I thought it hit so hard it would take out the universals.A true BANG every shift.The trans go is not quite that hard and there is no "bang" with it but it will bark the tires under medium throttle 1-2 shifts easily and all other gears are definately firmer to I even got a little bark from 2-3 sometimes.

A shift kit will not work right in a worn out tranny either how many miles on the tranny?

 

I have a Arr Carr kit in my worked T700.
Highest stagebefore full manual shift.
Was advised not to step up to larger boost valve (.500?) as too hard.
With stock boost valve , shifts VERY firm at part throttle , but sure as hell kicks **** at WOT.Super smooth / fast tyre chirping shifts .
Adjusting the shift via the TV cable is not the way tofit your problem.

 

Yes, it should be neck-snapping. Also, if you are driving in D, it may be neck-snapping when the tranny down-shifts into 1st. If you are in overdrive, it down-shifts gently. I'm not sure why, unless it's line-pressure.

 

Well here is a follow up.Appearently all the advice to adjust your TV cable according to the FSM is true.On ASR cars it entails putting a 1/8 in drill bit into the pulleys,release the 2 throttle cables and the TV cable,use a 1/4 drive w/extension and torque the pulleys to 8nm then flip the TV lock followed by flooring the throttle.I expected the installer to do this as he had the ASR covers off but after I did it all is well.Light throttle 1-2 shifts are firm but not neck snapping anymore.The gears wind out to ~5100rpm at WOT.Downshifts at 30mph into 1st above 30mph till 66mph it drops into 2nd.WOT from a stop will bark the tires very well into 2nd and a touch into 3rd.I like the Transgo better than the accumilator plugging shift trick it really does allow it to be smooth or rough depending on throttle position.It only cost me an extra $150 installed and makes the car run like a different vehicle.I have to recommend it.

 

Glad it all worked out. The devil is in the details sometimes. I was guessing (in the earlier reply) that the tv was the culprit. Looks like I was a lucky guesser

 

Thanks for your help Pete I suggest you get one of your "Cheap" customers to spring for the kit they and you will be impressed I am sure.

 

If no one will bite, I will put one in the trans I am building for a back up (for myself). I have heard too many good things about them not to try them. I like the thought of not barking the tires on each and every shift. When I was 20, the b&m kit seemed cool. Now, at close to 40, it is a bit annoying.
