Jackson , I am having this issue with my 1990 Cb7 Accord. What should I do ?

So lets try this a bit different. Either post what your car is doing and what you have checked and tested - there are a few in this thread - here. Or start a new one being sure to give the details.....what is the car doing, what you have tested, ect. |
There are actually 2 problems discussed in this thread..Which one do you have?

any place where I could the tran comp

Honda AT Control Unit Repair
HI, I realize this is an older thread. However, The origional response is spot on!
Eaglefixer My problem is the Capacitors & Resistors. I am in the process of sourceing these components. I was hoping to get a response from him. One of my Q? is that he never mentioned the value of the third resistor. Also wether he or anyone else had ever confirmed the actual value's of the 1st two resistors? Too bad noone has put together a repair kit containing these 8 parts. Seems that these are always exactly what's bad. Visibaly anyway mine were. |
It looks like one of the posters just copied and pasted the partial contents of this page:
techauto(dot)awardspace(dot)com/transmission(dot)html Just looking at the pic on that page shows R41 & R42 marked brown/green/black/gold: 15Ω/5%. You might be able to verify the color codes of the resistors on your printed circuit board if the resistors aren't too burned. This page might help if you find different colors:hobby-hour(dot)com/electronics/resistorcalculator(dot)php You can go 1% on the resistors. Either 1/4W or 1/2W would work, although you can either look at the spec sheet to see if a 1/2W will fit, or just order both since they're so cheap. The electrolytic caps should be clearly marked with capacitance and voltage ratings. You can always go up on the voltage rating as long as the cap still physically fits in the enclosure. Mouser or Dig-Key will have any part you need. |
More Info
That first site you listed is awsome.
Excellent post. Way to revive an old Thread. Anyone with this problem should definately consult techauto(dot)awardspace(dot)com/transmission(dot)html Also youtube (search) 91 Honda TCU (look for several posts by) tubejim101. Both Large resistors appear to be 15ohm. Its hard to tell because most pics are of burn ones or too blurry to say 100% But All leads point to 15. I am looking into the smaller resistor(s). Looks like my R46 & R47 may be Questionable. So I am likely to replace them as well as R43... |
Some fairly decent pic's here:
92 Accord Shifting Problems cb7tuner(dot)com/vbb/showthread(dot)php?t=169591 R43: BR/BL/OR? 10KΩ R46: BR/BL/OR? 10KΩ Or RD/BL/OR? 20KΩ R47: RD/BL/OR? 20KΩ I really can't tell for sure. You could pull one leg on each and measure them. If they're not completely open then with a DVM you should be able to tell the difference between 10K and 20K or whatever. |
Discrepancy
Strange.
With a Lighted Tech Mag Visor I can plainly see my colors on the Smaller resistors. I have the following R43 Yellow Orange Gold Gold 4.3 Ohm 5% R46 Yellow Violet Brown Gold 470 Ohm 5% R47 Brown Black Orange Gold 10K Ohm 5% Sometimes Brown might look red but compare with other resistors across the board and I think you will see that Red is much Brighter Red than what you are seeing on R47 resistor. For example R67 & R68 has red, orange, brown, & violet all close together which helps for comparison of band colors. Use these or some like them to compare and I believe you will come to the same conclusion. As to R46 You are coming up with a completely different combination. Wierd? I am looking right at it and YVBr are my colors. These are tiny resistors I belive they are 1/4 Watt could be 1/8 even. But can use higher will not hurt. Fit might be only problem R 41 & 42 are 15 Ohm at least 1/2 Watt. I went overkill on my Caps I ordered 50V Caps across the board for all 5 Replacements. Anyone else chime in on those resistors & Colors... Welcomed' |
Lol
Just realized you are likely looking at R81 which is Brown Black Orange
Look just above that resistor and just below what appears to be a Voltage Regulator and you should see the actual R43 which is infact Yellow Orange Gold |
I really can't make out the colors. When in doubt, pull a leg and measure the resistance.
