Working on my build now...was going to buy the foot press untill i looked at it and realized the clutch tool for my cfmoto atv fits..the way it is normally used for the case and the reverse drum. Then used the top of the tool in my press for the input..though buying the right bushing tool is a must.
Glad you were able to find something that works...Agree 100% on the bushing tools...I prioritize blind hole pullers and a master bushing driver set then accumulate specialized drivers for specific transmissions as I need them.
@@nickstransmissions whats your trick to remove the 3rd accumulator capsule from the case? Dont know if mines bad but getting replaced anyways, cheap insurance
Test it first, most are perfectly fine. No tricks, just use either an old bolt with slits cut into the threads or a removal tool. But test it after you hot-tanked the case. I bet it's not leaking...
Just finished rebuilding a 4L60e using your vids. I thought it went well, but apparently it did not. I have a super delayed 1-2 shift. Do you have any idea what I might have screwed up? Thanks for the awesome vids.
Thanks for watching, AB! I'd put a scan tool on it and look at both engine and transmission data... - Did you block off the isolator valve (or replace with an aftermarket equivalent) to convert the TCC PWM apply to on-off? - What is your servo travel and band clearance? - Did you install a shift kit or otherwise modify the 1-2 accumulator housing/piston, etc? - How did the air check for the servo during reassembly go? Late and harsh 1-2 upshift is usually indicative of a worn TCC regulator valve and is usually accompanied by coed P1870 or P0894 for later models. Excessive band clearance can result in a delay in the 1-2 shift but usually also presents with a slight flare or slip. Another possibility is something is not quite right w/the engine and or engine management sensors and/or data flows...For example the TPS and MAF or even vacuum leaks can result in misleading data being sent to the PCM. The PCM will act on that data and command the transmission accordingly. A few things to consider to get you started in your diagnosis...
@@nickstransmissions thanks so much for the response. After black friday traffic died down i test drove it again, and I think it is actually going to third from first, and I have a band or servo issue. First and reverse are both great. I will test for servo travel tomorrow. It is definitely an internal transmission issue and not engine management. While reviewing assembly vids today I did wonder if I possibly put the concave plate in the reverse input drum upside down, and what issue that would cause if I did?
Well apparently no issues...I have never put the rev-input belleville cusion plate upside down before but always theorized it would maybe result in a slightly harsh or bumpy reverse engagement if I had. Check servo travel....Also drop the pan and air check the servo (you'll need to drop the vb, spacer plate and both gaskets to gain access to the 2nd gear feed port). Test the 1-2 shift solenoid for continuity as well.
@@nickstransmissions dropped pan, band was in place, dropped valve body, had 4th apply, nothing from second apply. pulled servo. Found that somehow i managed to use the completely wrong o ring on second apply. was about 1/2 inch too short, didnt seal at all! I had dropped the correct one behind the workbench when i had to put project on hold for a couple days. Ordered the sonnax boost valve fix and some pinless accumulator pistons since they sonnax stuff was on sale through amazon and I had to disassembly valve body. I had done final assembly with the GM manual in the garage, and it has you install the servo last. Really shows the value of doing it in the order that you showed since you can test band apply that way! Thanks for all the help!
