    Engine sometimes acting strange. I'm all out ideas.

    Thanks! I did understand. If the issues should re-occur, i'll definitely give it a try.

    Engine sometimes acting strange. I'm all out ideas.

    Hi jesse, i tought the relearning procedure happened automatically every time the battery was disconnected long enough. Thanks for re-explaining. Next time i order parts, i"ll include and place a 195°F thermostat and see what happens. Now i don't see any change in coolant temperature when i'm on...

    Engine sometimes acting strange. I'm all out ideas.

    Prior to the problems I had my battery removed for a couple of days to repaint my rusted battery tray. Maybe this relearning of the IACV that Jesse mentioned was what happened. Anyway i took it for 3 (short) rides without any issues. It still smokes even when warm but that may have always been...

    Engine sometimes acting strange. I'm all out ideas.

    Hi guys, I have an occasional hesitation and sometimes it even stalls. I also notice that I have a lot of white-gray-ish smoke when cold and a little of it when warm and at idle. The smoke does not smell sweet, it smells like ordinary exhaust smoke. When I’m parked and at idle and give it gas a...

    Heavy vibration when accellerating slowly

    Thanks Chengnie. The transmission oil and filter are changed a couple of 1000 miles ago. The old oil was still in good condition and i did not notice any debries in the pan. I let it drip the whole night and installed the filter and fresh oil the next day. It did not solve the issue. I will try...

    Heavy vibration when accellerating slowly

    Since this thread hasn’t been updated for a while I recapliate in short. I have a very sudden speed related heavy and fast vibration (like driving over a washboard) when pulling up gently with the TC locked up in such a manner that it stays locked up. This happens always at the same speeds : 65...

    Stock V6 transmission in 1987?

    On 3th gen camaros the V6's and V8's TH700R4 are the same tranny's but they have different bolt patterns. Don't know about our squares though.

    Post your paint jobs.

    It took about 9 layers of paint on the hardtop to get the exact same colour as on the body.

    Weird hesitation issue

    About the stuttering, running over a wasboard, that's exactly what i'm experiencing with my '91. http://www.gmsquarebody.com/threads/heavy-vibration-when-accellerating-slowly.19322/ In 4th gear teh TCC is always on as long as you don't touch the brake and engine temp is above 149°F. My idle is...

    Heavy vibration when accellerating slowly

    Ok, i did all tests i could and found nothing wrong. The resistance of the solenoid is 30 ohm (must be more than 20). The current through it when it's on is 0,4 A. All tests of the flowchart were good meaning the solenoid comes on when it should and the 4th gear switch works as it should. All...

    Heavy vibration when accellerating slowly

    @chengny If you’re ever visiting Belgium, i’m gonna buy you a couple of bears, that’s for sure ! English is not my natural language, so i did not understand the concept ‘hot wiring’ fully, In my twisted mind that meant someting completely different :). So now i do and i will test it that way...

    Heavy vibration when accellerating slowly

    First off, thanks for the very great info on the previous post. i will print these schemas as i can read it better that way. Thanks ! It will be clear how to perform the test you proposed. The truck has had this issue ever since i bought it a couple of years ago but untill 3 months ago it was a...

    http://www.gmsquarebody.com/threads/rattle-in-oil-pan-below-700rpms.19010/ The ratlle was solved half way the thread. After that he developped a vibration very like mine.

    Rattle in oil pan below 700rpms

    @usar17 : i'm having the same issue, heavy vibration when locked up and trying to accelearte slowly (so the TCC keeps locked up). If the TCC unlocks the vibration stops. Is there a way to check ignition being good under load ?

    Heavy vibration when accellerating slowly

    Well that's an interesting thread. Turns out that the direct drive can make some issue more noticeable where some converter slip can mask a lot. I thinking i'm having the same problem but what ?

    Heavy vibration when accellerating slowly

    Ok, so i did the easiest test i could do which is disconnecting the TCC connector on the tranny. Drove it around town till the engine was at normal temperature and then headed for the highway. I could not create the vibration although doing many attemps. Then i reconnected the TCC at the tranny...

    Heavy vibration when accellerating slowly

    I thought that the "A" is always hot except for the brake witch (normal closed switch) and all other switches are downwards of the solenoid (going to mass - 0 V). So the only switch i would be bridging would be the brake witch ? You don't happen to have a schema on how the TCC is factory wired...

    Heavy vibration when accellerating slowly

    Man, this is a great forum! Thanks for the info. So here's my game plan : I will first disconnect the TCC solenoid connector like Yevgenievich said and see if the issue remains. BTW, is it ok for the TC to do 50 miles of highway without the TCC lock up installed considering the continious...

    Heavy vibration when accellerating slowly

    Yes, but don't know where the vacuum switch is located and if there is a delay valve or other stuff and how to test these things. Not an expert either :( No vacuum leaks. Vacuum is ok.

    Heavy vibration when accellerating slowly

    Hi guys, since I’ve been using this truck as a daily driver and doing a lot of highway driving this is starting to annoy me. Completely stock 1991 K5 350 with automatic transmission The short but very heavy vibration does not always occurs but if it does it’s always at following conditions ...

    350 Tbi running bad

    Hi, you mentioned that the back firing got slowly worse which makes me think it's a timing issue f.e. the distributor that turned slowly. When setting the timing, you did disconnect the tan wire and set the timing 0° right (see instructions on post 21)? Also, did you check if there are fault...

    How is 700r4 lock up controlled in a 1984?

    So if i don't brake, i won't disangage ? And do you think the issue i described is due to this?

    How is 700r4 lock up controlled in a 1984?

    Does anyone know how the lockup is triggered to disconnect? I use my '91 K5 with stock 700R4 as a daily driver which includes a lot of highway driving. When crusing at 75 mph and have to slow down a little f.e to 70 mph and then when traffic in front of me clears up and i push in the gas pedal...

    What Are the Symptoms of a Bad 700R4 Governor?

    I'm not an expert on tranny's but here's what i experienced. I had the same issue and adjusted the tv-cable 10 times according procedures (you know with the clicks at full throttle). Still i found the shifts rather hard especially 1-2. Then i read somewhere that the tv-cable on the 700r4 often...
