I am going to be putting a TransGp shift kit into my 700-R4. Anyone who has one of these: How has the performance of your car changed in rain? I am worried that the new "snappy shifts" may be dangerous. Perhaps you could describe how the shifting changes after putting one of these kits in.

So I guess that means no increase in the frequency of peel-outs or fish-tailing, etc... (as long as you are careful)... I am going to go ahead with the installation of the TransGo kit.

Yeah, since the tranny's line pressure is controlled in part by the TV cable, which is linked to the throttle assembly, how hard your foot is in the gas has a big effect on how hard the tranny shifts. This is especially true with the Trans Go. When I'm barely on the throttle, I get a firm but by no means neck snapping shift. At about 1/4 throttle I get a firm and quick shift, sometimes enough to give a little chirp. At full throttle, I always get a chirp that lasts for about half a second, and the car goes a little sideways as well. In rainy weather (when I choose to drive in it, I try to avoid it), I just keep out of the throttle and there is no problem.

BTW to the dude who replied first, it's not necessary to capitalize every word.

I'm curious on how much that shift kit cost. Where did you get it? Let me know if you ran into any problems installing it and what you think of it. Also with a shift kit can I now scratch 3rd in my 88 GTA 5.0?

The shift kit costs $130 dollars. And no, you will not be able to scratch the 2-3, since it occurs at 90+mph. I get a firm 2-3, but no scratch.

 

90+ mph at the end of 2nd??? What kind of gear are you running???

 

2.73s. 2-3 shift at 90mph. 1-2 comes at 45.

Mr.J-

Thats a pretty high gear, I know that my car redlines way before 90mph when hitting 3rd. 90mph is like when I'm hitting 4th. If you really wanted to wake that car up you should put a lower gear in it. I wanted to put a 3.77s in my car but I have that weird Australian 9 bolt and gears are pretty exspesive.

Believe it or not, I don't mind the 2.73s that much. They give an AWESOME downshift from a roll, especially in the 25-40mph range. I'm more inclined to get a better converter, with a higher stall and greater torque multiplication, and get similar results to a gear swap that way. In the 1/4 mile, I shift into 3rd about 1 second before crossing the MPH traps.

 

You know that's kinda odd. I've got 2.77 gears and i hit ninety in the top of third gear. I Think your not counting a gear or something. To run ninety in second gear you'd need lower than 2.77 gears or some monster tall tires.

 

If he has an auto he isn't far off. I have 3.42's and my first ends at about 35 or so and second at about 67-70 and i have had third to about 105 but that is it for third. I have driven an 89 IROC with 2.77 gears and first ended at like 52 or something wayyy up there and second ended at i am guessing 87 or so because we broke 80 in second like it was nothing and we still had another 600rpm till redline. But that was a 350 with the 5500 rpm redline but still 80 at 4900 rpm in second.

Believe what you will. I'm running 245/50/ZR16s on all corners. If you hit 90 at the top of third then you sure as hell don't have 2.77s.

 

I believe it since my IROC had 2.73's. With the 5000 rpm redline, I'd hit 80 mph or so in 2nd gear. The TCC is forced to lock around 77 mph, so what BP89IROC is feeling is the TCC locking up, not the tranny shifting into 3rd gear. I had my IROC on the road up to 125 mph in 3rd gear with the 2.73's (engine was revving about 4800 rpm), and hit 131 mph at 5000 rpm on a chassis dyno. Now with 3.42's, it shifts into 2nd gear around 63-64 mph, just before the 1/8-mile marker, letting the engine pull 3rd gear to the traps, going through them at 4300-4400 rpm.

With my B&M Shift Improver Kit, if I baby the throttle (normal driving), I can't feel the 1-2 shift at all. It's only when I'm pushing the car... I'd wager a guess at feeling the 1-2 shift around 3,000 rpm & up.

I had my TH350 rebuilt and it shifts thru all 3 gears by the time I hit 40mph or sooner. But they are pretty solid shifts, scratch the tires in 2nd all the time. I also routinely run my motor up to 6000 on the tach, I have no idea how fast I'm going cause the gears in the TH350 are wrong for the speedo and that only goes to 85mph anyways. Anyone have any idea how fast I'm going at 6 grand with 3.42 gears in the back? I have a rebuilt 350 .060 over etc. Thanks.

I have the B&M kit in my car and even if I am driving with the throttle at just over idle the 1-2 shift snaps the car.
Driving normal also makes the car shift into 4th at about 65-70.
Tom have you adjusted your TV cable? I know if I back mine off then it doesn't shift hard at all, and it up shifts quick. I'll be in 4th gear by 40 under normal driving.
And as far as driving in the rain, even under very light throttle, the rear end slides a little on the 1-2 shift... going around a corner.. I really have to pay attention. And in snow ( no I am no happy about it but have no choice ) it doesn't matter how little throttle, the rear is out about 90 degrees on the 1-2 shift.

MrJ is right about his gears and MPH.

I run an A4 and 2.73, and my trans shifts right about 5000rpm, (probably a little lower than MrJ's) and first gear ends at 40mph and second ends at 80mph. I can easily see that he shifts at 45 and 90 with a few hundred more RPMs than I have.

 

By the way, MrJ

What RPMs do you shift at? I got a GM Reman Transmission and the governor in it was actually a little lower than my original one. I now shift just above 5k RPMs

 

I manually shift 1-2 at 5300 RPM, and 2-3 at around 5100 RPM. What's odd is, even with the 5000 RPM tach, the tranny will shift 1-2 at 5100 all by itself. Keep in mind though that stock tachs are often somewhat inaccurate, so I could be actually shifting at a higher or lower RPM than I think I'm shifting at.

HEY, save yourself some headache and get your tranny rebuilt before you install that kit. the increase in pressure will likely destroy all of your old seals within weeks. took mine two weeks to go out after installing a transgo shift with under 75,000 average miles on it.

it's a great improvement though. i have 3.73 gears and it will sometimes scratch from 1-2 even if i'm just rollin slow through a parking lot. it's great!!! just have to get my transmission rebuilt now 3rd and 4th are non existant right now, and let me tell you it sucks running around town with 3.73 ratio and only 1st and 2nd!
