4l60e No Manual First Only
4l60e No Manual First Only I have a transmission I bought from BMR Transmissions (Biggest mistake ever) and after everything is done, I don't have manual first gear. All other gears shift fine, the transmission has first gear when in drive, converter locks up, everything else feels fine and shifts good.
Does anyone have any ideas on what may be causing the transmission to start in second gear when the transmission gear selector is in first.
The car does not engine brake when shifting from second to first. There is no difference or shift felt when shifting from first to second.

have you confirmed the linkage isn't off slightly and it is not engaging first?
if the selector is off just fractions of an inch it will go into 2nd and not make the full travel into the 1st gear detent, this would cause the car to start in 2nd gear rather than first and shift to second
i have this problem with my b&m shifter as over time the cables will stretch enough to prevent the shifter from moving the lever on the transmission enough to click into the 1st detent

The console has a spot for 1, 2, 3, D, N, R, and P. BMR will not answer their phone due to a problem with the transmission from the beginning so do not buy for BMR transmissions they're horrible.
Thunderstruck, how would I go about checking if the linkage is off. Is there any adjustment for the ball bracket thing that connects on the side of the transmission. I have just the stock shifter not a B&M shifter if that matters. Thanks for the responses.

Verdad Gallardo like he said, jack that car up (on stands for safety) and put the shifter in "1", then crawl under the car and pay real close attention to the position the linkage is in
then disconnect the cable from the linkage and see if you can move the linkage another click (I want to say the linkage will swing towards the rear of the car)
either way, that's the only excuse I can think of it would have first in D but not in manual low

Update: Got under the car today to check the linkage. When the car is in 1st on the selector, the lever is all the way back so I assumed there was no adjustment needed. The lever is all the way back and it still starts out like it is in second gear. I manually moved the lever from 2nd to 1st and form 1st to 2nd and there was no change in the movement of the tires or sound of the motor like it switched gears.
I manually moved the gear from 3rd to 2nd and 2nd to 3rd and there was a difference in the tire movement and sound of the motor. Anyone have any ideas on what the problem may be. Transmission still shifts fine and has first gear in manual 3rd and drive just not in manual 1st.

Please refer to this similar and recent thread:
https://ls1tech.com/forums/automatic...lem-fixed.html
I listed possible internal problems, but it turned out to be a misadjusted shifter. If you are sure the trans is in [D1], then as mentioned in that thread, I would check out these possibilities in order:
1. Manifold pressure switch ($30 and very easy to replace)
2. Valve body ($100 used or $150 rebuilt; a few hours to replace)
3. Internal problem with the low/reverse clutch
OR - Just don't use [D1]; I never have.

Thanks for the ideas! As far as an internal problem, if there is a problem with the low/reverse clutches would there also be a problem with reverse or is it possible to still have reverse functioning properly?
